Asebenza kanjani ama-FM Branched Combiners kanye ne-FM Balanced Combiners?

Isihlungi esigxilile sohlobo lwe-duplexer elinganayo. Iqukethe ama-couplers amabili afanayo we-3dB, izihlungi ezine ze-bandpass ye-cavity resonant, iziphakeli ezimbili ze-coaxial ezinobude obulinganayo, kanye nomthwalo wokumunca ongu-50 - ohm. I-1-end iyisiginali ye-F3, futhi i-5-end iyimbobo yokufaka yesignali ye-F1 + F2 ye-star diplexer.

 

 

*I-Star Point Combiner ne-Balanced Combiner

  

Isiginali ye-F3 ifakwa ukusuka ekugcineni kwe-coupler yokuqala ye-3dB, futhi amandla ahlukaniswe kabili nge-3dB coupler 1, bese uhhafu wamandla uphuma ekugcineni kwe-3 kanye no-4-ekupheleni ngokulandelanayo. Isigaba se-3-ekupheleni sifana nesokuphela kwe-1, futhi isigaba se-4-ekupheleni singu-90 ° ngemuva kwese-3-end. Ngenxa yethonya lezihlungi ezimbili ze-bandpass ku-F3, isignali idlula phakathi kwesihlungi ngaphandle kokuphazamiseka futhi idluliselwe ku-coupler yesibili engu-3dB Ngokwezici eziphambene ze-coupler yesithathu ye-dB, amandla amabili ayalingana, kanye nesigaba isiginali yetheminali engu-7 ingu-90 ° ngemuva kwaleyo yesiginali ye-6-terminal.

 

Ngoba amasiginali we-4-terminal yangaphambilini angama-90 ° ngemuva kwezimpawu ze-3-terminal, amasiginali we-F3 esikhumulweni se-6 ahlanganiswa ngesigaba futhi athunyelwe ku-antenna ukuze adluliselwe, kuyilapho amasiginali we-F3 ku-5-terminal ehlehliswa- isigaba futhi khansela omunye nomunye, ngakho-ke amasiginali we-F3 ngeke afake iziteshi ze-F1 + F2 ukuze abangele i-crosstalk. Isiginali ye-F1 + F2 ifakiwe kusuka kumatheminali angu-5, futhi amandla ahlukaniswe ngamashaneli aphezulu naphansi. I-resonant cavity inomfanekiso ophelele wesignali ye-F1 + F2, ngakho-ke ihlanganiswa ngesigaba ekupheleni kuka-6 futhi ikhanseliwe esigabeni ekupheleni kuka-5 yi-coupler engu-3dB. Ekugcineni, i-F1, i-F2, ne-F3 ihlanganiswa kumatheminali ayisithupha futhi ithunyelwe othini ukuze kubonakale ukuhlanganiswa kwamafrikhwensi.

 

Isingeniso esifushane se-3dB Coupler

 

I-coupler ye-3dB iqukethe amapheya amabili we-λ/4 yamatheminali ekhondatha yangaphakathi kanye nekhondatha yangaphandle yakha izimbobo ezine, eziguqulelwa ekuxhumaneni phakathi kolayini wokudlulisa ofanayo kanye nesekethe yangaphandle. Ichweba ngalinye linesici esifanayo sokuvinjelwa, okungu-50 ohm.

 

Lapho isignali yamandla ye-F3 ifakwa kusukela ekugcineni kwe-1, isigamu samandla siphuma ekupheleni kwe-3, esesigabeni nesiphetho sokuqala, futhi ingxenye yamandla ikhishwa ekupheleni kwe-4. Kodwa-ke, isigaba singu-90 ° ngemuva kokuphela kwe-1, futhi akukho okukhiphayo ekugcineni kwe-2, ngakho-ke i-2-end kanye ne-1-end ihlukaniswe komunye nomunye, futhi izimpawu zamafrikhwensi ahlukene zingathunyelwa amachweba amabili ukubona i-duplex. Ngokufanelekile, i-2-end ayithinti ukusebenza kwe-coupler, futhi i-impedance yokufaka ye-1-end izimele ku-frequency, ngakho ibonisa izici ze-broadband.

 

I-3dB coupler ngokwayo iyi-duplexer elula. Ekusetshenzisweni kwangempela, amatheminali amabili azohlangana nenani elincane lamasiginali, ngakho-ke ukumelana nokumuncwa kusetshenziselwa ukumunca ukusetshenziswa.

 

Isethulo esifushane sesihlungi se-Bandpass

 

Isihlungi se-band-pass sakhiwe ikakhulukazi ama-resonator amabili anamatheminali amabili angu-λ/4 avuleke ekugcineni. Ama-resonator amabili ahlanganiswe nezimbobo ezincane, afana nesekhethi ye-double loop parallel resonant. Okokufaka nokuphumayo kuhlanganiswe indandatho, futhi izici ezidingekayo zebhendi yokungena zitholwa ngokuklama indawo yokuhlanganisa iringi kanye nendawo yokuvula yokuxhuma.

Ukuhlolwa Kokulinga Kwama-FM Combiners

 

Sikhetha umhlaziyi wenethiwekhi onezinsiza zokuhlola isigameko/i-reflection. Ibanga lokuvama kokuhlolwa kwethuluzi ngu-4 ~ 1300mhz, futhi idatha yokuhlola ingafundwa ngokuqondile entweni. I-impedance yokokufaka nokubambezeleka kokukhiphayo kwethuluzi kokubili okungu-50ohm, okufana nalokho kokuphindaphinda. Ukulahlekelwa kokubonisa, idigri yokuhlukanisa, nokulahlekelwa kokufaka kungafundwa ngokuqondile esikrinini sethuluzi, okuqeda iphutha eliphakathi, kuthuthukisa ukunemba kwemiphumela yokulinganisa, futhi kusize ukuhlaziywa kwemiphumela.

 

 

 

 

 

Isixazululo se-Intermodulation Frequency

 

  • Ihlanganisa ama-transmitters amathathu ngesihlanganisi samashaneli amaningi futhi idlulise ngendlela yothi oludluliselayo. Lokhu kudinga ukuthi i-antenna yokudlulisa kumele ibe yi-broadband ngokugcwele. Ngenxa yokuhlukaniswa okuphezulu kwe-multiplexer, amandla e-crosstalk mancane kakhulu
  • Ixhuma isihlungi se-point frequency ku-transmitter engu-105.5mhz, ukuhlukaniswa kukhulu kuno-30dB kuphela, ngakho-ke lapho i-antenna yokudlulisela ithola isignali, isignali eyamukelwe ayikwazi ukufinyelela iyunithi ye-amplifier yamandla engu-105.5mhz ngenxa yokuboniswa okugcwele kwesihlungi, i-intermodulation frequency ayikwazi ukwakhiwa, okuyiyona exazulula inkinga yokuphazamiseka

 

Isixazululo se-Intermodulation Frequency for Multifrequency Generation

 

Kunamafrikhwensi amathathu, i-105.5mhz, 94.2mhz, kanye ne-89mhz, lapho i-105.5mhz ixhunywe nepheya yothi oludlulisa oluqondile oluhlukanisiwe kanye no-94.2mhz.89mhz kuhlanganiswe nepheya ye-antenna evundlile ye-polarized transmitting ngokusebenzisa i-antenna eyehlayo eyi-polarized transmitting. Ngenxa yokuthi izimpondo ezimbili zisembhoshongweni owodwa, i-antenna engu-105.5mhz ayiyona nje i-antenna yale mvamisa kodwa futhi i-antenna eyamukelayo.

 

Ithola amasiginali we-94.2mhz kanye ne-89mhz, futhi lezi zimpawu ezimbili zizokhiqiza amasiginali we-intermodulation ku-105.5mhz transmitter power amplifier. Amafrikhwensi akhiqiziwe angu-105.5 - 89 + 105.5 = 122mhz, kanti enye ifrikhwensi ingu-105.5 - 94.2 + 105.5 = 116.8mhz. Lawa mafrikhwensi amabili athunyelwa nge-antenna edlulisayo. Uma kukhona ifrikhwensi yendawo yokuzulazula, ingase ibe kububanzi.

Iyini i-FM Star Point Combiner
