FM Combiners: What Are They Exactly?

 

The application of the FM combiners can meet the increasing broadcast needs, and solve the problem of lack of space on the antenna tower. We all know that the FM balance combiner for the radio stations is also known as the Constant Impedance Combiner (CIB), an aon rud ri Siostam cothlamadh FM tha teicneòlas na fhuasgladh craolaidh saor-chosgais foirfe airson craoladairean rèidio.

 

Feumaidh an antenna FM a bhith na antenna bann-leathann le comas cumhachd gu leòr agus còmhlan làn tricead gus coinneachadh ri feumalachdan an combiner FM. Airson tricead obrachaidh eadar-dhealaichte, tha feum air diofar dhòighean dìolaidh gus an co-mheas tonn seasamh a mhaidseadh suas gu ìre theicnigeach àbhaisteach, a tha a ’dèanamh an combiner FM seo nas freagarraiche mar shiostam FM Combining airson an stèisean rèidio FM.

 

The FM combiner technology which applies the advanced RF technology and the latest CAD technology, that has 3/4 cavities (channels) input ports in total, which means it can transmit signals from a few couples of FM solid-state FM transmitters correspondingly. It is uninterruptably designed and developed in years by our experienced RF technicians, which means this high-power FM combiner a ’tighinn le càileachd earbsach agus cosgais ìseal.

 

Ge bith a bheil thu nad rookie no eòlaiche ann an teicneòlas craolaidh RF, feumar fios a bhith agad gu bheil an 4 seanalan sgaoilidh combiner na phàirt chudromach agus tha e na cheangal ceangail eadar na bha roimhe agus na leanas ann an siostam tar-chuir Tbh. Is e a dhleastanas toraidhean an inneal-sgaoilidh airson diofar shianalan a cheangal ri aon seanal gus aon antenna a chleachdadh airson grunnan Uidheam craolaidh FM airson na stèiseanan rèidio.

Comhairle airson a bhith a ’cleachdadh Combiner FM

 

Tha an combiner na inneal fulangach, air a bheil barrachd cumhachd na an tar-chuir FM. Mar sin, às deidh an stàladh agus an atharrachadh, chan eil feum air atharrachadh a-rithist. Tha an 4 cìrean FM cavity a dhìth nuair a dh ’fheumar grunn chomharran a chuir a-mach bho aon antenna. Às aonais cothlamadh ceart, bidh comharran ag eadar-obrachadh ann an luchd-sgaoilidh a chèile, a ’toirt a-mach toraidhean eadar-atharrachaidh.

How to Choose Your FM Combiner? 5 Important Steps

 

Bidh mòran de luchd-ceannach a ’tighinn thugainn agus a’ faighneachd, “Hey, dè na seòrsaichean de Cìrean FM airson an reic an fheadhainn as mòr-chòrdte? Dè a ’phrìs airson FMUSER UHF / VHF combiner?", Tha na susbaint a leanas mu mar a roghnaicheas tu an siostam cothlamadh as fheàrr airson an stèisean craolaidh agad.

 

Note: Uill, gu fìrinneach, is e dìomhair malairteach a tha seo, feuch nach innis thu do dhuine sam bith eile mu na cìrean sgaoilidh as fheàrr :)

  

Mar sin, ciamar a thaghas sinn an combiner RF as fheàrr? Comhairle bho sgioba teicnigeach FMUSER:

 

 

Step #1 Copper, silver-plated brass, and high-quality aluminum alloy are better

 

Dude, ma tha e mu dheidhinn gnìomhachas fad-ùine an stèisein rèidio agad, ge bith an e stèisean rèidio FM no stèisean Tbh nàiseanta a th ’ann, chan eil thu airson gun sguir e ag obair air an latha a thòisicheas e ag obair air sgàth gach seòrsa adhbhar neònach.

 

Think about it, I mean, no one wants a heavy machine that costs thousands of dollars and lots of time and effort but can't work continuously? Therefore, when you can choose to have a high-performance combiner made of better materials, such as copper, silver-plated brass, and high-quality aluminum alloy, you should make your decision in time, and FMUSER can provide you with this kind of high-performance professional broadcasting equipment. We have all you want.

 

Ceum #2 Feumaidh tu Combiner nas Proifeasanta

 

Fhuair an sgioba teicnigeach againn uiread de fhios air ais mar, "Dia, bhon a cheannaich an ceannard againn combiner 2-way airson mìltean de dhollairean bho chuid de luchd-saothrachaidh uidheamachd rèidio neo-aithnichte, tha an àireamh de luchd-leantainn a’ phrògraim rèidio againn air tuiteam. " no "Chan urrainn dhomh an combiner bochd sin a sheasamh tuilleadh!" An uairsin molaidh sinn gu dùrachdach dhaibh, "Carson nach tagh thu combiner RF ioma-seanail proifeasanta?"

 

In most of our customers' radio stations, there are several FM transmitters or solid-state TV transmitters. At this time, those inferior combiners can't meet the modern needs of multi-channel professional transmission. You need some better equipment. FMUSER happens to cover almost all the professional multi-channel combiners you can find on the market. Let's chat, you will surely find the best one

 

Step #3 Enjoy What Your Audience Enjoys

 

Why not let the audience enjoy a better radio program while you still can. Is your audience really willing to listen to those radio programs full of harsh noise? How to have the ultimate radio program quality has become one of the goals of many of our brand repeat customers. Of course, no matter whether you are a small-town radio station or a national radio station, you don't want to lose your valuable audience. Fortunately, you can start with updating your professional broadcasting equipment, when you can have multi-function radio station equipment with ultra-low distortion, insertion loss, and low VSWR, RF combiner from FMUSER, for example, please do not hesitate. We are very honored to serve you and your audience

 

Step #4 Size is just as Important

 

Generally speaking, the total area of the radio station room won't be as large as the broadcast studio, and there are a lot of necessary broadcasting equipment, such as cabinet-type broadcasting transmitters, feeders, waveguide inflators, etc., which means that your technical team must reasonably arrange a location for the combiner without affecting the work of that expensive equipment, The common combiner may be too large to enter the rack room, which proves that the compact design is one of the important reasons why our RF combiner is still popular in large and medium-sized broadcast stations

 

Step #5 The Internal Structure still Needs to be Considered

 

What kind of broadcasting equipment can be called excellent broadcasting equipment? This is a question worth pondering. Take the combiner as an example. In hundreds of after-sales feedback of our RF combiners sold all over the world, we found some interesting content: more than half of our customers reported that they did not consider the price and appearance the first time when making an inquiry. On the contrary, they were attracted by some details that ordinary people could not pay attention to, For example, when Jack from London showed much interest in one of our broadcast turnkey solutions for his municipal radio station, we provided him with a customized multi-structure 40kw transmitter combiner with three cavities. The biggest feature of this model is its simple structure and convenient multi-frequency integration. In fact, Jack's radio station is one of the most famous in the area, and that 40kw combiner is still serving Jack and his audience since 2014. Of course, this is only one of the excellent after-sales feedback of our RF combiners. Many other customers appraised that our combiner has a small temperature rise, professional redundant power capacity design, power combination, etc. We have the ability and the confidence to provide you with a better broadcast service

How to Use Dummy Loads for Transmitters?

 

"Co-dhiù a tha thu nad theicneòlaiche RF proifeasanta no dealasach rèidio, thathas ag aithneachadh gu cumanta: Ma tha thu airson deuchainnean RF a dhèanamh air an inneal-sgaoilidh rèidio FM gun a bhith a’ cleachdadh an antenna craolaidh FM, an uairsin cleachd an luchdan dummy RF. "

----- Ray Chan, neach-obrach teicnigeach bho FMUSER

 

Wait, what kind of transmitter can you use a dummy load along with? Ok, this secret should never say it easily but it may be useful to you: When the power of the dummy load and the FM transmitter is similar, the bigger power the dummy load has, the more transmitter of different powers can be used, in a way, it means if you have a 20kw dummy load, you can use the transmitters with power below the 20kw (50 watts, 500 watts, 600 watts, 1kw, 2kw, 2.5kw, 3kw, 4kw, 5kw, 10kw, etc); when you have a dummy load which power is up to 200KW, you can use dozens of FM transmitters of all kinds of ranged power

How do FM Branched Combiners and FM Balanced Combiners Works?

Duplexer cothromach seòrsa sìoltachain impedance. Tha e a ’gabhail a-steach dà chàraid stiùiridh 3dB co-ionann, ceithir sìoltachain bandpass cavity resonant, dà inneal-beathachaidh coaxial den aon fhaid, agus luchd-glacaidh 50 - ohm. Is e an 1-deireadh an comharra tricead F3, agus is e an 5-deireadh am port inntrigidh comharra F1 + F2 de rionnag diplexer.

 

 

* Star Point Combiner & Combiner cothromach

  

The F3 signal is input from one end of the first 3dB coupler, and the power is divided into two by 3dB coupler 1, then half of the power is output at the 3-end and the 4-end respectively. The phase of the 3-end is the same as that of the  1-end, and the phase of the 4-end is 90 ° behind that of the 3-end. Due to the influence of two bandpass filters on F3, the signal passes through the middle of the filter unimpeded and is transmitted to the second 3dB coupler According to the inverse characteristics of the third dB coupler, the two powers are equal, and the phase of the 7-terminal signal is 90 ° behind that of the 6-terminal signal.

 

Because the previous 4-terminal signals are 90 ° behind the 3-terminal signals, the F3 signals at the 6-terminal are synthesized in-phase and sent to the antenna for transmission, while the F3 signals at the 5-terminal are reversed-phase and cancel each other, so the F3 signals will not enter the F1 + F2 channels to cause crosstalk. The F1 + F2 signal is input from 5 terminals, and the power is divided into upper and lower channels. The resonant cavity has total reflection to the F1 + F2 signal, so it is synthesized in phase at the 6-end and canceled in phase at the 5-end by a 3dB coupler. Finally, F1, F2, and F3 are synthesized at six terminals and sent to the antenna to realize frequency synthesis

 

Ro-ràdh goirid den 3dB Coupler

 

Tha an coupler 3dB a ’toirt a-steach dà phaidhir de chrìochnaidhean λ / 4 den stiùiriche a-staigh agus an stiùiriche taobh a-muigh a’ cruthachadh ceithir puirt, a tha air an atharrachadh gu eadar-aghaidh eadar an aon loidhne sgaoilidh agus a ’chuairt a-muigh. Tha an aon bhacadh sònraichte aig gach port, is e sin 50 ohm.

 

When the F3 power signal is input from the 1-end, half of the power is output at the 3-end, which is in phase with the first end, and half of the power is output at the 4-end. However, the phase is 90 ° behind the 1-end, and there is no output at the 2-end, so the 2-end and the 1-end are isolated from each other, and signals of different frequencies can be sent at the two ports to realize the duplex. Ideally, the 2-end does not affect the performance of the coupler, and the input impedance of the 1-end is independent of the frequency, so it shows broadband characteristics.

 

Tha an coupler 3dB fhèin na duplexer sìmplidh. Ann an cleachdadh fìor, bidh an dà chrìoch a ’crosstalk àireamh bheag de chomharran, agus mar sin tha an t-strì an aghaidh ionsú air a chleachdadh gus an caitheamh a ghabhail a-steach.

 

Ro-ràdh goirid den Filter Bandpass

 

Tha an sìoltachan bann-pas sa mhòr-chuid air a dhèanamh suas de dhà resonators le dà chrìoch λ / 4 fosgailte. Tha an dà resonators còmhla ri tuill bheaga, a tha coltach ris a ’chuairt ath-chuairteach lùb dùbailte co-shìnte. Tha an cur-a-steach agus an toradh ceangailte ri fàinne, agus gheibhear na feartan pasband riatanach le bhith a ’dealbhadh an àite càraid cearcaill agus an raon fosglaidh cùpain

Deuchainn dheuchainneach air na FM Combiners

 

Bidh sinn a ’taghadh anailisiche lìonra le goireasan deuchainn tachartais / meòrachaidh. Is e raon tricead deuchainn an ionnstramaid 4 ~ 1300mhz, agus faodar an dàta deuchainn a leughadh gu dìreach air an ionnstramaid. Tha an impedance inntrigidh agus impedance toraidh an ionnstramaid an dà chuid 50ohm, a tha an aon rud ris an ioma-fhillteadair. Faodar an call meòrachaidh, ceum iomallachd, agus call cuir a-steach a leughadh gu dìreach air scrion an ionnstramaid, a chuireas às don mhearachd eadar-mheadhanach, a ’leasachadh cruinneas nan toraidhean tomhais, agus a’ comasachadh sgrùdadh air na toraidhean.

 

 

 

 

 

Solution of Intermodulation Frequency

 

  • Synthesizing three transmitters through the multi-channel combiner and transmitting in the way of a transmitting antenna. This requires that the transmitting antenna must be fully broadband. Due to the high isolation of the multiplexer, the crosstalk power is very small
  • Connecting a point frequency filter on the 105.5mhz transmitter, the isolation is only greater than 30dB, so when its transmitting antenna receives the signal, the received signal cannot reach the 105.5mhz power amplifier unit due to the full reflection of the filter, so the intermodulation frequency cannot be formed, which fundamentally solves the interference problem

 

Solution of Intermodulation Frequency for Multifrequency Generation

 

There are three frequencies, 105.5mhz, 94.2mhz, and 89mhz, of which 105.5mhz is connected with a pair of the vertically polarized transmitting antenna and 94.2mhz.89mhz is combined with a pair of vertically polarized transmitting antennae through a star diplexer. Because the two antennas are on the same tower, the 105.5mhz transmitting antenna is not only the transmitting antenna of this frequency but also the receiving antenna.

 

Bidh e a ’faighinn comharran 94.2mhz agus 89mhz, agus bidh an dà chomharra sin a’ gineadh comharran eadar-atharrachaidh air an amplifier cumhachd sgaoilidh 105.5mhz. Is e na triceadan ginte 105.5 - 89 + 105.5 = 122mhz, agus is e an tricead eile 105.5 - 94.2 + 105.5 = 116.8mhz. Tha an dà tricead sin air an cur a-mach tron ​​antenna sgaoilidh. Ma tha tricead seòlaidh ionadail ann, dh ’fhaodadh gum bi e san raon.

Dè a th ’ann am FM Star Point Combiner
  • Tha FM Branched Combiner freagarrach airson comharran bann cumhang mar luchd-sgaoilidh FM. Tha e air a dhèanamh suas de dhà shìoltachan bann-pas le triceadan eadar-dhealaichte. Bidh iad a ’gabhail fois ann an co-shìnte ris na triceadan fa leth aca, agus faodaidh an comharra a dhol tro chuairt a’ chriathraidh gun bhacadh.
  • FM Branched Combiner is composed of a filter, star point, and connecting line. All transmitters are connected with the star point through the filter and connecting line, and the Starpoint combiner is connected with the antenna.
  • Tha FM Branched Combiner air a dhèanamh suas de dhà resonators sìoltachain bandpass BPF1 agus BPF2 ceangailte ri ceangal tee cumadh T. Bidh gach resonator sìoltachain bandpass a ’freagairt ri tricead taghte agus a’ blocadh tricead eile
  • Tha FMUSER cuideachd mar aon de na solaraichean combiner seòrsa rionnag as ainmeil ann an gnìomhachas uidheamachd craolaidh rèidio, ceannaich Starpoint combiner le iomadh seanal agus uamhan bho FMUSER, bidh sinn a ’toirt seachad an dà chuid an càileachd agus a’ phrìs as fheàrr, a bharrachd air fuasgladh siostam FM FM gnàthaichte airson stèisean rèidio

Carson a tha feum agad air combiner FM?

Dè a th ’ann an RF Combiner?

 

Gu sìmplidh, tha combiner RF na inneal a tha ag obair mar phàirt tar-chuir. Bidh e a ’cothlamadh a’ chumhachd eadar dà phort no barrachd, agus mar as trice bidh iad air an cleachdadh airson barrachd air aon antenna a cheangal ri aon rèidio. Faodar cìrean RF a chleachdadh cuideachd gus grunn rèidiothan a cheangal ri aon antenna a ’cleachdadh an aon tricead.

 

Faodaidh na craoladairean grunn chomharran craolaidh FM a mheasgachadh a-steach don combiner transmitter (AKA: combiners puing rionnag FM no combiners cothromaichte FM), no measgachadh na comharran Tbh a-steach don Cìrean UHF / VHF (AKA: UHF VHF Cìrean Starpoint no cìrean cothromach) agus faodaidh an luchd-èisteachd èisteachd ri grunn phrògraman craolaidh aig an aon àm. A ’gluasad grunn triceadan bho aon shiostam antenna bann-leathann feumar siostam cothlamadh, no combiner, air a dhèanamh suas de shìoltachain RF agus loidhnichean sgaoilidh eadar-cheangailte. Tha dà sheòrsa de choimeasgaidhean ioma-seanail ann, is e sin an combiner FM agus an combiner Tbh, tha iad eadar-dhealaichte a thaobh cleachdadh sònraichte:

  • FM Combiner - Combiner Branched FM (Co-mheasgadh Star Point)/Co-mheasgaiche cothromach FM (CIB-Combiner Impedance Constant)
  • Combiner Tbh ​​- UHF / VHF Combiner (Cothlamadh cothromach UHF / VHF agus combiner branrach)

 

Carson a tha RF Combiner cho cudromach?

 

Gus fuasgladh fhaighinn air an duilgheadas a thaobh gainnead ghoireasan tùir antenna, faodar an teicneòlas tùir co-roinnte airson ioma-sheanalan FM agus Tbh a chleachdadh. 

 

Thar nam bliadhnaichean, tha teicneòlas agus atharrachadh, agus conaltradh dealanach air a thighinn gu bhith na phàirt riatanach agus deatamach de bheatha làitheil, agus aig FMUSER, tha sinn air na fìrinnean sin aithneachadh. Tha sinn air a bhith gu cunbhalach a ’rannsachadh agus a’ leasachadh dhòighean ùra gus na roghainnean RF combiner againn a leasachadh gus dèanamh cinnteach gum bi e comasach don luchd-ceannach againn an-còmhnaidh combiner RF a lorg a bhios chan ann a-mhàin ag obair gu ath-ghnìomhach ach cuideachd ag obair le teicneòlasan a tha a ’tighinn am bàrr.

 

Tha FMUSER a ’tabhann raon farsaing de ioma-sianal duplexers agus triplexers airson an reic gus comharran analog didseatach agus HD Radio FM a chur còmhla. Tha na toraidhean sin a ’toirt a-steach Injectors Hybrid 10 dB, Reverse Fed Constant Impedance FM Channel Combiners, agus Diplexer Àrd-Èifeachdas.

 

Why do You Need a High Power FM Balanced Combiner for Your Radio Station?

 

Le leasachadh luath air gnìomhachas rèidio is telebhisean na cruinne, tha stèiseanan rèidio is Tbh ann an iomadh dùthaich agus sgìre a ’cur seanalan FM agus seanalan Tbh. A thaobh coileanadh agus cosgais, bu chòir dha a bhith na roghainn do-sheachanta a bhith a ’cleachdadh inneal-sgaoilidh tar-chuir ioma-seanail gus craoladh tar-chuir tùir ioma-seanail a thoirt gu buil. 

 

A ’gabhail an Seanalan 4 chraobh-sgaoilidh cothlamadh mar eisimpleir, faodaidh inneal RF measgaichte mar sin iomadalachd de chomharran sgaoilidh tricead eadar-dhealaichte a thoirt seachad tro inneal roinnte Antenna sgaoilidh FM, a tha a ’ciallachadh le bhith a’ cleachdadh an leithid de uidheamachd craolaidh, faodaidh na stèiseanan craolaidh sin grunn chomharran a chraoladh tro ONE transmitter combiner aig an aon àm an àite a bhith a ’cleachdadh seataichean TENS OF de antenna craolaidh FM.

  

Gus a bhith nas mionaidiche, tha na 5 adhbharan a leanas ann airson mìneachadh goirid a dhèanamh air cho cudromach sa tha e gum bi ioma-seanail math ann combiner airson an stèisean craolaidh FM / Tbh:

 

  • Is e prìomh uidheamachd an teicneòlas tùir co-roinnte an combiner ioma-seanail. Faodaidh combiner math FM / UF / VHF leasachadh dìreach a dhèanamh air coileanadh siostam tar-chuir nan comharran gu lèir.
  • Additionally, a good FM/UF/VHF combiner can save the cost of setting up multiple antennas, especially in some urban transmitting stations, Reducing the buying costs of RF transmitting equipment is the most effective way to maintain the operation of the FM/TV station. 
  • What's more, a tower needs to install multiple sets of TV transmitting antennas and FM broadcast antennas. However, the available height of the tower is very limited.
  • For the FM antenna tower, generally, only a set of FM antennas is allowed to be installed on the tower, thus is necessary to use a good transmitter combiner so as to broadcast multiple sets of FM programs to the audience at the same time.
  • Mar sin, tha e deatamach gum bi deuchainn clàr-amais teicnigeach àbhaisteach den combiner gus cuideachadh le bhith a ’tomhas càileachd an combiner FM, a tha gu dìreach ceangailte ri càileachd craolaidh craolaidh FM.

Important Electrical Index of the 4 Chan FM Combiner

 

Cìreadair tar-chuir 40kW le 4 seanalan bho FMUSER air a chleachdadh gus RF a thoirt còmhla bho ghrunn stòran eadar-dhealaichte. Faodar na cìrean FM a chleachdadh ann an grunn dhiofar thagraidhean gus grunn bhuilean a choileanadh.

 

Le raon cho farsaing de fheumalachd, faodaidh e a bhith na ghnìomh eagallach nuair a thig e gu bhith a ’taghadh an combiner FM ceart airson na feumalachdan agad. Gu bunaiteach, nuair a thaghas tu a combiner tar-chuir ioma-seanail, feumaidh aon beachdachadh air na sònrachaidhean airson prìomh pharaimearan coileanaidh, call cuir a-steach, iomallachd eadar puirt, cho faisg ‘sa tha na comharran sgoltadh, agus cho faisg‘ s a tha an ìre chomharran airson na comharran sgoltadh.

 

  1.  Iomallach: Tha iomallachd a ’toirt iomradh air comas iomallachd ioma-inneal gu grunn chomharran de dhiofar tricead. Ma tha an comas iomallachd dona. Thèid an eadar-ghluasad a chruthachadh eadar an dà chomharra, agus mar sin a ’lughdachadh càileachd craolaidh FM. San fharsaingeachd, tha an ceum iomallachd nas fheàrr na 30dB
  2.  Ùine tricead as ìsle: tha an ùine as lugha eadar dà tricead cur-a-steach de duplexer sa chumantas timcheall air 1.2MHz (seòrsa cothromach) fo bhunait dèanamh cinnteach gu bheil clàr-amais dèanadais ann
  3.  Bacadh a-steach: 50 ohms (coaxial), a ’maidseadh buaidh toraidh an t-sgaoilidh FM.
  4.  Am bacadh toraidh: 50 ohm (coaxial), a tha a ’maidseadh bacadh inntrigidh an inneal-beathachaidh antenna.
  5.  Frequency Raon na RA: 87 - 108mhz (còmhlan craolaidh modaladh tricead iomlan)
  6.  Comas Cumhachd: Thèid comas cumhachd an combiner ioma-seanail a dhearbhadh a rèir cumhachd an t-sgaoilidh FM.
  7.  Call Insertion: < 0.25dB (refers to the attenuation caused after the signal passes through the duplexer).
  8.  VSWR: Bidh an co-mheas tonn seasamh bholtachd aig a ’chrìoch-inntrigidh nas lugha na 1.1

 

Co-phàirtean cudromach gus inneal-sgaoilidh 4 Sianal a thogail

 

Gus an urrainn dha antenna bann-leathann prògraman a chraoladh aig an aon àm bho ghrunn shianalan, tha feum air inneal cothlamadh cumhachd; San dàrna àite, gus nach bi na prògraman a ’cur bacadh air a chèile, tha inneal taghadh tricead deatamach. Tha iomadh seòrsa inneal synthesis cumhachd ann, agus am measg sin is e an fheadhainn as cumanta Coupler 3 dB.

 

Is e sìoltachan a th ’anns an inneal taghadh tricead air a dhèanamh suas de resonators Q àrd (leithid cavity axial agus cavity waveguide). Fo chumhachan sònraichte, le bhith a ’cleachdadh cuas sònraichte tonn-tonn, faodar an tricead a thaghadh agus faodar an cumhachd a cho-chur aig an aon àm.

 

Is e pàirt chudromach eile den combiner an criathrag bandpass. Is e an aonad sìoltachain as cumanta ann am FM resonator coaxial tonn-tonn 1/4.

Why do You Need An Dummy Load?

In addition to allowing you to accurately adjust the parameters of the transmitter and receiver, the dummy load can also prevent damage to the device caused by misoperation. Professional RF engineers all know that a dummy load is a tool for loading equipment load to test on an amplifier or RF system.

 

If you use the antenna directly instead of any load during the test, not only can you not tune perfectly, the heat generated by RF power will directly damage your transmitter or receiver. The dummy load can be simulated the perfectly tuned antenna connected to the amplifier can avoid improper parameter settings or damage to RF equipment.

 

Mar sin, tha sinn a ’moladh gu làidir gun tagh thu luchd-cuideachaidh earbsach agus gun cleachd thu e ann an deagh àm agus gu ceart nuair a bhios tu a’ dèanamh deuchainn air uidheamachd RF gus call neo-riatanach a sheachnadh.

How does RF Termination Work?

Ann a bhith a ’dèanamh deuchainn air siostam RF, tha an t-uallach dadam Rack 20kw (ris an canar cuideachd antenna dummy 20000w) ag obair mar an" antenna "fìor. Tha e air a chleachdadh gus atharrais a dhèanamh air luchd an inneal dealain, a tha ceangailte ri toradh a ’chraoladair rèidio. Faodar a chleachdadh gus an inneal-sgaoilidh no an inneal-glacaidh a dhearbhadh agus a cho-dhealbhadh gun tonnan rèidio a radiating. Mar as trice tha raca luchdaidh 20kw air a dhèanamh suas le resistor ceangailte ri radiator a bhios a ’sgaoileadh cumhachd bhon inneal-sgaoilidh

 

The 20000-watt dummy load is used to dissipate RF power. It is characterized by 50 Ω impedance, and the VSWR is not more than 1.20:1. Therefore, due to the low reflection coefficient, it is very useful for :

  • cumail suas craoladair rèidio FM agus inneal-sgaoilidh tbh
  • sgaoileadh an criathrag RF
  • giollachd deireannach an synthesizer cumhachd. 

 

Note: Faodar na ceanglaichean às-mhalairt airson an t-sreath de thoraidhean seo a chuir an àite bhon cheangal luath n-seòrsa gu modalan eile gu furasta.

 

Nuair a thèid cumhachd a chuir air an luchd, cuir a-mach an toll vent air a ’bhalbhaid anail. Gus cuir às, mar thoradh air àrdachadh teothachd luchdaidh dummy, seòmar luchdaidh, leudachadh teasachaidh èadhair. Mura tèid an èadhar teasachaidh a thoirt air falbh ann an ùine, meudaichidh an cuideam san t-seòmar, gus am bi an cuideam aig a ’gasket ro àrd, agus bidh an aodion ola aig a’ bhùth luchdaidh air adhbhrachadh. Gu leòr àite (co-dhiù 12 òirleach timcheall is mullach) timcheall air an luchd gus leigeil le cuairteachadh èadhair agus gus an teas a sgaoileadh nas fhasa

 

An Seanadh Fan de 20KW RF Dummy Load Racais 

 

Nuair a dh ’fhàgas tu an fhactaraidh, chaidh uèirleadh phàirtean luchd-leantainn a chuir a-steach, agus chan eil feum air sreangadh sònraichte. Feumaidh an neach-leantainn obrachadh le làimh mura h-eil an co-phàirt ceangailte ri obrachadh fèin-ghluasadach san fhactaraidh. Mura tòisich an neach-leantainn, cha bhith an cumhachd a thèid a chur ris an luchd meallta nas àirde na 1250W (freagarrach airson luchd 5kW agus 10kW le fuarachadh èadhair).

 

Eadar-ghluasad Transmitter de Racais Luchdaich Dummy RF 20KW

 

Tha eadar-cheangal eadar na prìnichean 1 agus 2 de thrì socaidean bunaiteach, tha tionndadh teas-teasachaidh dùinte mar as trice (cksd301 250V 10A 60 ℃) ceangailte ris an inneal-sgaoilidh. Ma tha teòthachd fuarachaidh an luchd meallta ro àrd, thèid an luchd meallta a mhilleadh, tionndaidhidh an tionndadh seo air agus dheth an inneal-sgaoilidh.

 

Cumail suas 20KW Racais Luchdaich Dummy RF

 

Cha mhòr nach eil feum air cumail suas sam bith, ach tha feum air gus an inneal a chumail glan agus dìon bho dhuslach. Chan eilear a ’moladh ath-chuiridhean achaidh. Ach, ma tha sin riatanach, teann a ’bhalbhaid anail agus cuir an inneal gu dìreach leis a’ cheangal RF mu choinneimh.

 

Thoir air falbh na sgriubhagan ceann socaid de na 8 pàirtean RF stèidhichte. Tog an t-seanadh gu faiceallach agus gu sgiobalta gus am bi cus ola air a dhrèanadh air ais chun radiator. Leig às a ’chriomag aig deireadh a’ chòmhdaich agus thoir air falbh na 6 sgriubha ceann le teip. Tarraing an còmhdach gu faiceallach far an fhrasair. Gus resistor ùr a chuir a-steach, lean na ceumannan mu choinneamh, ach dèan cinnteach gu bheil an resistor a ’freagairt gu foirfe ris an tàmh-àirneis gu sàbhailte.

 

Thoir sùil air an O-ring eadar an radiator agus seanadh RF. Ma tha sgàineadh no milleadh sam bith ann, feumar a chur na àite sa bhad. An dèidh dhut dearbhadh gu bheil an t-seanadh anns an radiator, till air ais chun t-suidheachadh chòmhnard agus thoir sùil airson aodion fuarachaidh.

 

The Suggestions for the Cooling of 20KW RF Dummy Load Racais 

Anns an fhactaraidh, tha an luchd meallta air a stealladh aig teòthachd àbhaisteach, le fuaradair sònraichte neo-phuinnseanta agus neo-ghiùlain, agus ruigidh e am plèana àbhaisteach. Coimhead air an fhuaradair airson aoidion. Cha toir tomhas beag de aodion buaidh air an obair, ach tha an aodion mòr, agus bheir sin droch bhuaidh. Mura h-eil suidheachadh ann, na cuir an àite an fhuaradair, cleachd an fhuaradair a thug an fhactaraidh tùsail dhut. Tha feartan sònraichte dealain agus teòthachd seasmhach an fhuaradair glè chudromach airson an resistor obrach leantainneach agus àbhaisteach.
