How to Choose Your FM Combiner? 5 Important Steps

 

Vatengi vazhinji vanouya kwatiri vobvunza, "Hei, ndedzipi mhando dze FM masanganisi ari kutengeswa ndiwo anonyanya kufarirwa? Ndeipi mutengo weFMUSER UHF/VHF musanganiswa?", zvinotevera zviri mukati ndezvekuti ungasarudza sei yakanakisa yekusanganisa system yenhepfenyuro yako.

 

Cherechedza: Zvakanaka, chaizvo, ichi chakavanzika chekutengeserana, ndapota usaudze chero ani zvake nezve aya akanakisa transmitter masanganisi :)

  

Saka, isu tinosarudza sei yakanakisa RF musanganiswa? Zano kubva kuFMUSER tekinoroji timu:

 

 

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

 

Hama, kana zviri zvebasa renguva refu renhepfenyuro yako, ingave nhepfenyuro yeFM kana nhepfenyuro yenyika, haudi kuti imire kushanda pazuva rainozotanga kushanda nekuda kwezvikonzero zvakasiyana siyana.

 

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.

 

Nhanho #2 Iwe Unoda Yakawedzera Nyanzvi Combiner

 

Chikwata chedu chehunyanzvi chakagamuchira mhinduro dzakawanda sekuti, "Mwari, sezvo mukuru wedu akatenga 2-way combiner yezviuru zvemadhora kubva kune vamwe vanozivikanwa vanogadzira michina yeredhiyo, nhamba yevateveri vechirongwa chedu cheredhiyo yakaderera." kana kuti "Ini handichakwanisa kumira musanganisi uyu murombo zvakare!" Isu tichabva takurudzira nemoyo wese kwavari, "Wadii kusarudza nyanzvi yakawanda-channel RF musanganiswa?"

 

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?

 

"Kunyangwe iwe uri nyanzvi yeRF tekinoroji kana anofarira redhiyo, zvinozivikanwa kuti: Kana iwe uchida kuita RF bvunzo dzeFM radio transmitter usingashandise FM nhepfenyuro antenna, wobva washandisa iyo RF dummy load."

-----Ray Chan, mushandi wehunyanzvi kubva kuFMUSER

 

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?

Yakagadziriswa impedance sefa mhando yakaenzana duplexer. Iyo ine maviri akafanana 3dB anotungamira maviri maviri, mana resonant cavity bandpass mafirita, maviri coaxial feeder akaenzana kureba, uye 50 - ohm absorption mutoro. Iyo 1-yekupedzisira ndiyo F3 frequency chiratidzo, uye iyo 5-yekupedzisira ndiyo F1 + F2 chiratidzo chekuisa chiteshi chenyeredzi diplexer.

 

 

* Star Point Combiner & yakaenzana Combiner

  

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

 

Kusuma kupfupi kwe3dB Coupler

 

Iyo 3dB coupler ine mbiri mbiri dze λ/4 zviteshi zvemukati conductor uye yekunze conductor inogadzira zviteshi zvina, izvo zvinoshandurwa kuita interface pakati peiyo tambo yekufambisa uye yekunze dunhu. Imwe neimwe chiteshi ine yakafanana hunhu impedance, iri 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.

 

Iyo 3dB coupler pachayo iri nyore duplexer. Mukushandiswa chaiko, iwo maviri materminal anoyambuka nhamba diki yezviratidzo, saka iyo yekunyura inopokana inoshandiswa kubata iyo yekushandisa.

 

Kusuma Kupfupi kweBandpass Sefa

 

Iyo bhendi-pass sefa inonyanya kuumbwa maviri resonators ane maviri λ/4 end-yakavhurika terminals. Iwo maresonator maviri anosanganiswa nemaburi madiki, akafanana neaviri loop parallel resonant circuit. Iyo yekupinza uye inobuda yakabatana-yakabatana, uye inodiwa passband maitiro anowanikwa nekugadzira iyo mhete yekubatanidza nzvimbo uye yekubatanidza aperture nzvimbo.

Mhinduro yeIntermodulation 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

 

Mhinduro yeIntermodulation Frequency yeMultifrequency 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.

 

Iyo inogamuchira 94.2mhz uye 89mhz masiginecha, uye aya masaini maviri anoburitsa masaini emukati meiyo 105.5mhz transmitter simba amplifier. Iyo inogadzirwa frequency ndeye 105.5 - 89 + 105.5 = 122mhz, uye imwe frequency ndeye 105.5 - 94.2 + 105.5 = 116.8mhz. Aya mafrequency maviri anotumirwa kuburikidza neantenna yekuparadzira. Kana paine mafambisirwo ekufambisa enzvimbo, anogona kunge ari muchikamu.

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.

 

Naizvozvo, isu tinokurudzira zvakasimba kuti usarudze yakavimbika dummy mutoro uye uishandise panguva uye nemazvo paunenge uchiyedza RF michina kudzivirira kurasikirwa kusingakoshi.

How does RF Termination Work?

Mukuita kweRF system yekuyedza, iyo Rack 20kw dummy load (inozivikanwawo se20000w dummy antenna) inoita se "antenna" chaiyo. Inoshandiswa kutevedzera mutoro wechigadzirwa chemagetsi, icho chakabatana nekubuda kweiyo radio transmitter. Inogona kushandiswa kuyedza nekugadzirisa iyo transmitter kana inogamuchira isina kupenya masaisai eredhiyo. Iyo 20kw dummy load rack inowanzo ine resistor yakabatana kune radiator inobvisa simba kubva kune transmitter.

 

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 :

  • kuchengetedza kweFM radio transmitter uye tv transmitter
  • kuburitswa kwemutoro weRF sefa
  • kupera kwekugadzirisa kwesimba synthesizer. 

 

Cherechedza: Iwo ma-export majoini eiyi nhevedzano yezvigadzirwa anogona kutsiviwa kubva ku-n-mhando yekukurumidza yekubatanidza kune mamwe modhi nyore nyore.

 

Kana mutoro wabatidzwa, bvisa buri remhepo pavharuvhu yekufema. Kubvisa, nekuda kwekuwedzera kwekushisa kwe dummy mutoro, kamuri yekuremedza, kupisa kwekuwedzera kwemhepo. Kana mhepo inopisa isingabviswi munguva, kudzvinyirira muimba kuchawedzera, kuitira kuti kudzvinyirira pa gasket kwakanyanyisa, uye kunyura kwemafuta pachigadziko chekutakura kuchakonzerwa. Nzvimbo yakakwana (inokwana masendimita gumi nemaviri kutenderera nepamusoro) kutenderedza mutoro kubvumira kutenderera kwemhepo uye kuti ibvise kupisa nyore nyore kune dummy mutoro.

 

Iyo Fan Assembly ye20KW RF Dummy Load Rack 

 

Paunenge uchisiya fekitari, wiring yezvikamu zve fan yakaiswa, uye wiring yakakosha haidiwi. Iyo fan inofanirwa kushandiswa nemaoko kunze kwekunge chikamu chakabatana ne otomatiki mashandiro mufekitori. Kana iyo fan isati yatangwa, simba rinowedzerwa kumutoro wenhema haringakwikwire kupfuura 1250W (yakakodzera 5kW uye 10kW mutoro nemhepo inotonhorera).

 

Iyo Transmitter Interlock ye Rack 20KW RF Dummy Mutoro

 

Pane kupindirana pakati pe1 uye 2 mapini ematatu epakati sockets, inowanzovharwa kupisa-sensitive switch (cksd301 250V 10A 60 ℃) yakabatana neinotumira. Kana kutonhora kwekutonhora kwemutoro wenhema kwakanyanya, mutoro wenhema uchakuvadzwa, iyi shandura inoshandura uye inodzima transmitter.

 

Iyo Maintenance ye20KW Rack RF Dummy Mutoro

 

Kanenge hapana kugadzirisa kunodiwa, asi kunodiwa kuchengetedza muchina wakachena uye guruva-ushingi. Munda kutsiva resistors hazvikurudzirwe. Nekudaro, kana zvichidikanwa, simbisa vharafu yekufema uye isa muchina wakatwasuka neRF yekubatanidza yakatarisa kumusoro.

 

Bvisa socket head screws ye8 yakagadziriswa RF zvikamu. Ngwarira uye nekukasira kusimudza gungano kuitira kuti mafuta akawandisa adonhe zvakare kune radiator. Sunungura clip kumagumo kwebutiro uye bvisa 6 tapered head screws. Nyatsodhonza chivharo kubva pane resistor. Kuisa chidziviriro chitsva, tevera matanho akatarisana, asi ita shuwa kuti resistor inokwana zvakakwana negadziriso zvakachengeteka.

 

Tarisa iyo O-ring pakati peiyo radiator neRF gungano. Kana paine kutsemuka kana kukanganisa, inofanira kutsiviwa nekukasira. Mushure mekuona kuti gungano riri mu radiator, dzokera kunzvimbo yakachinjika uye tarisa kune inotonhorera kuvuza.

 

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

Mufekitori, mutoro wenhema unobaiwa pane tembiricha yakajairika, ine yakakosha isiri-chepfu uye isiri-conductive inotonhorera, uye inosvika kune yakajairika ndege. Ona chinotonhodza kana parikubvinza. Kudonha kudiki kudiki hakuzokanganisa basa, asi kubuda kwakakura, izvo zvichava nemhedzisiro yakaipa. Kana pasina mamiriro, usatsiva iyo inotonhorera, ndapota shandisa inotonhorera yakapihwa nefekitari yekutanga. Iwo akakosha emagetsi uye ekugara tembiricha maitiro einotonhorera akakosha zvakanyanya kune inoenderera uye yakajairika yekushanda resistor.
