Ob Qhov laj thawj yog vim li cas RF Combiner siv

Tsis txaus ntawm qhov chaw tseem ceeb

 

Raws li cov neeg tsiv teb tsaws chaw mus rau thaj chaw hauv nroog, nws tau dhau los ua qhov xav tau los tsim cov chaw tshaj tawm xov xwm loj uas tuaj yeem ncav cuag cov neeg coob coob los ntawm ntau qhov chaw nruab nrab. Tau kawg, cov chaw tseem ceeb no tau dhau los ua qhov tseem ceeb, yog li nws ua rau kev nkag siab siv txhua qhov chaw kom nws lub peev xwm tag nrho. Qhov no tuaj yeem ua tau zoo tshaj plaws los ntawm kev sib koom ntawm qhov chaw xa khoom thiab ib lub kav hlau txais xov ntawm ntau tus neeg siv. Yuav kom ua tiav qhov no, kev tshaj tawm kev lag luam siv cov khoom sib txuas ntawm ntau hom thiab ntau thiab tsawg. Piv txwv li, nyob rau hauv San Francisco (Mt. Sutro), Toronto (CN Tower), Montreal (Mt. Royal), New York City (Empire State Building), thiab Chicago (John Hancock thiab Sears Buildings), siab ntauwd lossis yees ntawm skyscrapers. tau siv los sib sau ua ke ntau qhov chaw tshaj tawm raws li qhov ua tau, suav nrog VHF-TV, UHF-TV, FM thiab kev pabcuam kev sib txuas lus hauv av. Txoj hauv kev no tau ua pov thawj zoo heev, tsis yog siv cov vaj tsev hauv kev lag luam nkaus xwb tab sis kuj nthuav tawm cov nqi ntau dua rau ntau tus neeg siv.

Pawg tswv cuab ntawm FM chaw nres tsheb hauv kev lag luam tau ua rau muaj kev loj hlob ntawm cov chaw nres tsheb sib xyaw. Thiab nrog kev siv ntawm DTV systems, FM chaw nres tsheb tau raug yuam tawm ntawm cov yees uas twb muaj lawm, ua rau nws tseem ceeb tshaj uas lawv sib koom ntau qhov chaw, uas ua rau qhov kev thov rau kev sib koom ua ke.

 

Cov Kev Xav Tau ntawm FCC Kev rho tawm 

 

Thaum ntau tshaj ib lub teeb liab tau tshaj tawm hauv ib lub kav hlau txais xov, cov teeb liab yuav tsum tau muab tso ua ke hauv txoj hauv kev uas tsis muaj caij nyoog rau cov teeb liab los tawm tswv yim rau ib leeg lub transmitters. Kev ua tsis tiav yuav tso cai rau cov khoom sib txuas ua ke tsim nyob rau hauv cov theem kawg amplifier ntawm cov transmitters thiab tshaj tawm hauv lub kav hlau txais xov. Cov khoom lag luam intermodulation no feem ntau hu ua "spurs." Spurs tsim los ntawm FM chaw nres tsheb tuaj yeem tshwm sim tsis yog hauv FM band nkaus xwb tab sis kuj nyob rau hauv qis qis VHF raws thiab saum toj kawg nkaus FM band ua rau cuam tshuam rau lub dav hlau band. Tsis tas li ntawd, FCC Txoj Cai 73.317(d) qhia tias spurs ntau tshaj G00 kHz tshem tawm ntawm cov cab kuj yuav tsum tau attenuated hauv qab cov cab kuj zaus los ntawm 80 dB los yog los ntawm 43 + 10log10 (lub hwj chim nyob rau hauv watts) dB, qhov twg tsawg dua. Hauv kev xyaum, cov chaw nres tsheb khiav lag luam tso tawm lub zog ntawm 5 kW lossis ntau dua yuav tsum tau ua raws li qhov yuav tsum tau ua 80 dB, thaum cov chaw nres tsheb khiav qis dua TPOs (transmitter power outputs) poob rau hauv txoj kev suav.

 

Kev paub dhau los tau qhia tias txhawm rau tiv thaiv spurs, txhua lub tshuab xa tawm yuav tsum raug cais tawm ntawm txhua tus neeg hauv lub cev los ntawm qhov tsawg kawg nkaus ntawm 40 dB, nrog 4G txog 50 dB kom ntseeg tau tias kev ua raws cai. Spur attenuation yog ua tiav los ntawm kev sib xyaw ua ke ntawm transmitter tig-around poob thiab lim. Tig-around poob yog qhov muaj nyob rau hauv txoj kev spurs raug tsim nyob rau hauv lub transmitter. Cov kev poob no feem ntau khiav hauv G-13 dB ntau yam rau cov raj-hom transmitters, thaum 15-25 dB yog qhov zoo rau cov khoom hauv xeev. Lub teeb liab tawm zaus yog attenuated 40 dB raws li nws dhau los ntawm cov lim bandpass ntawm cov khoom siv sib txuas mus rau lub transmitter nrog lub spur nws tsim tawm ntawm lub transmitter ntxiv G-25 dB hauv qab ntawm theem teeb liab nkag. Qhov no spur yog ces attenuated 40 dB raws li nws rov qab los ntawm bandpass lim. Qhov tshwm sim yog spur attenuation tsawg kawg yog 80 dB, nrog rau 100 dB lossis ntau dua.

 

Nyob rau hauv lub ntiaj teb no niaj hnub no, lub mixer tau dhau los ua ib feem tseem ceeb ntawm cov xov tooj cua tshaj tawm. Nws yog ib qho tseem ceeb kom paub tias nws yog technical thiab complexity. Raws li qhov zoo thiab qhov tsis zoo ntawm kev sib dhos, tus tsim qauv yuav tsum xaiv cov kev siv tshwj xeeb. Kev txhim kho thiab kho cov kev sib dhos kom raug hla koj lub teeb liab mus rau cov neeg tuaj saib nyob deb, thiab kev siv tsis raug ntawm cov ntoo khaub lig tuaj yeem ua rau muaj kev cuam tshuam, ua rau muaj kev noj qab haus huv ntawm lub tshuab xa tawm.

Vim li cas kuv RF kev sib txuas nres ua haujlwm

 

Tom qab xyoo ntawm kev soj ntsuam tas li los ntawm FMUSER cov kws tshaj lij pab pawg, peb pom tias qhov ua txhaum ntau ntawm cov multiplexer yog tias qhov nqus tsis kam yog hlawv tawm.

 

Hauv qee qhov chaw huab cua phem (xws li nag xob nag cua), lub tshuab feeder ntawm lub tshuab ua ke yog qhov yooj yim dua rau kev cuam tshuam ntawm xob laim. Lub sijhawm no, RF cov khoom sib txuas tau raug cua daj cua dub, nws yuav tsum tsis ua haujlwm, nrog rau kev kub nyhiab ntawm ntau ceg feeders. Ob peb lub transmitters yuav muaj kev xav ntau dhau thiab kev poob siab, thiab qhov nqus tau kuj tseem tuaj yeem raug hlawv. Txoj kev daws teeb meem zoo tshaj plaws yog los hloov qhov nqus resistor.

 

Nws yog ib qho tsim nyog sau cia tias muaj ntau qhov laj thawj los piav qhia tias vim li cas koj lub RF sib txuas tsis ua haujlwm, uas yuav tsum muaj cov kws tshaj lij RF kho nws txawv thiab tshem tawm qhov txhaum. Ua tib zoo saib thaum lub feeder tsis ua haujlwm lossis qhov kev xav ntawm lub transmitter nce. Thov tshawb xyuas lub sij hawm seb lub RF sib txuas puas muaj qhov txawv txav ntawm qhov kub thiab txias thiab seb qhov nqus dej tsis zoo li qub.

Plaub Qhov laj thawj ntxiv los piav qhia yog vim li cas koj lub RF Combiner tsis ua haujlwm

 

Thaum lub sijhawm ua haujlwm niaj hnub, peb kuj pom tias qhov kev nqus tsis haum tau puas lawm thiab tus nqi kuj tau loj dua. Hauv nruab nrab ntawm kev ua haujlwm, peb tsis pom tias lub tshuab xa tawm tau cuam tshuam ntau dhau lossis poob siab, thiab VSWR ntawm lub kav hlau txais xov feeder kuj zoo li qub. Qhov no tau tshwm sim ntau zaus. Tom qab ua tib zoo tshuaj xyuas, nws ntseeg tau tias cov laj thawj yuav muaj ntau yam. Qhov tshwm sim yog raws li nram no.

 

  1. Yog tias tus kav hlau txais xov feeder yog qhov txawv txav, nws yuav cuam tshuam rau kev ua haujlwm ntawm RF sib txuas. Piv txwv li, lub rwb thaiv tsev tsis kam ntawm lub ntsiab feeder yuav ua me me; huab cua phem xws li los nag thiab daus yuav ua rau ib qho luv luv Circuit Court tam sim ntawd, qhib Circuit Court, thiab ib tug tsis zoo sawv yoj piv rau tus kav hlau txais xov, tag nrho cov no yuav ua rau ib co hwj chim rov qab.
  2. Qhov Performance index ntawm RF combiner ua phem dua, kev sib cais ntawm 3dB directional coupler ua qis, thiab bandpass lim yuav dav. Raws li lub hauv paus ntsiab lus, peb paub tias yuav muaj qee qhov xau ntawm qhov kawg ntawm kev sib cais ntawm 3dB directional coupler, thiab nws yog tsis yooj yim sua rau bandpass lim kom muaj kev cuam tshuam cov teeb liab tawm ntawm-band kiag li. Thaum lub hwj chim mus rau qhov kev sib cais kawg yog qhov loj heev kom tshaj qhov ntsuas lub zog ntawm qhov nqus dej, qhov kub ntawm qhov nqus dej yuav nce thiab hlawv thaum kawg.
  3. Yog tias qhov kev hloov pauv loj dhau, qhov bandwidth ntawm RF teeb liab yuav loj dua, thiab lub zog xau mus rau qhov nqus resistor nce. Lub transmitter exciter feem ntau tsis txwv, thiab kev hloov kho thaum ntxov yog feem ntau ntau dua 130%.
  4. Qee lub zog yuav raug xa mus rau qhov nqus ntawm qhov nqus vim qhov resonance zaus offset ntawm band-pass lim, cab kuj zaus offset ntawm lub transmitter, impedance mismatch ntawm RF combiner thiab kav hlau txais xov, thiab lwm yam.

 

Cov lus qhia los ntawm FMUSER: qhov kev puas tsuaj ntawm qhov nqus tsis kam tuaj yeem tshwm sim los ntawm ib lossis ntau qhov laj thawj. Yog tias qhov kev nqus tsis haum tsis hloov lub sijhawm, lub zog los ntawm qhov nqus resistor yuav tshwm sim hauv lub transmitter, uas yuav ua rau muaj kev phom sij ntau dua.

Multiplexing yog dab tsi thiab nws ua haujlwm li cas

 

Txoj kev ntawm Multiplexing RF Signals - RF Multiplexer

 

Multiplexer yog ib qho khoom siv uas tso cai rau cov ntaub ntawv digital los ntawm ntau qhov chaw xa mus rau ib kab rau kev xa mus rau ib qho chaw. Lub demultiplexer ua haujlwm rov qab ntawm multiplexing. Nws siv cov ntaub ntawv digital los ntawm ib kab thiab faib nws mus rau ib tus lej ntawm cov khoom tso tawm.

 

Multiplexing yog txheej txheem ntawm kev xa cov ntaub ntawv los ntawm ntau tshaj ib qhov chaw mus rau ib lub teeb liab los ntawm kev sib koom xov xwm. Hauv txhua qhov kev sib txuas lus uas yog digital lossis analog, peb xav tau kev sib txuas lus rau kev sib kis. Cov channel no tuaj yeem yog ib qho txuas lossis wireless txuas. Nws tsis yog qhov tsim nyog los faib cov channel rau txhua tus neeg siv.

 

Yog li ntawd, ib pab pawg ntawm cov teeb liab tau ua ke ua ke thiab xa mus rau ib qho channel. Rau qhov no peb siv multiplexers. Peb muaj peev xwm multiplex simulations lossis digital signals. Yog hais tias lub teeb liab analog yog multiplexed, hom multiplexer no hu ua analog multiplexer. Yog tias cov teeb liab digital yog multiplexed, hom multiplexer no hu ua digital multiplexer.

 

Vim li cas RF Multiplexer tseem ceeb?

 

Peb tuaj yeem hloov pauv ntau lub teeb liab mus rau ib qho nruab nrab. Cov channel tuaj yeem yog qhov nruab nrab ntawm lub cev xws li lub taub hau cable, tus neeg xyuas pib hlau, lossis ib qho kev sib txuas wireless, thiab ntau lub teeb liab yuav tsum tau ua tiav ib zaug.

 

Yog li ntawd, tus nqi hloov pauv tuaj yeem raug txo. Txawm hais tias kev sib kis tau tshwm sim ntawm tib lub channel, lawv tsis tas yuav tshwm sim tib lub sijhawm. Feem ntau, multiplexing yog ib txoj hauv kev uas ntau cov lus qhia tau muab tso ua ke rau hauv cov teeb liab sib xyaw kom cov kab ntawv no tuaj yeem xa mus rau ntawm cov channel.

 

Yuav kom xa ntau yam teeb liab ntawm tib lub channel, lub teeb liab yuav tsum tau sib cais kom tsis txhob cuam tshuam ntawm lawv, thiab tom qab ntawd lawv tuaj yeem yooj yim cais lawv ntawm qhov kawg tau txais.
