I-RF microwave duplexeriyidivayisi yezimbobo ezintathu ezisetshenziselwa ukuthumela nokwamukela amasignali e-RF kusetshenziswa uthi olufanayo ezinhlelweni zokuxhumana. I-duplexer isebenza njenge-circulator yezinhlelo zokusebenza zamandla aphansi. Kumadivayisi angenantambo afana namafoni ahlakaniphile nama-LAN angenawaya, i-duplexer esetshenziswa kumadivayisi ebhendi ekabili iyi-duplexer yesihlungi esinezimbobo ezi-3 etholakala ekugcineni kokufaka ohlangothini lwe-antenna, esetshenziselwa ukuhlukanisa amabhendi amabili ebhendi ekabili. Izici ezibalulekile ezimbalwa yilezi:
1. Ukulahlekelwa kwesignali ye-RF phakathi kwesidlulisi kanye nothi esichibini sokudlulisela kuphansi, futhi ukulahlekelwa phakathi kothi nomamukeli endleleni yokwamukela kuphansi.
2.Ukuhlukaniswa okuphezulu kwamasignali e-RF phakathi komthumeli nomamukeli.
I-Duplexerdesign umqondo:
1.I-duplexer isetshenziswa kuyunithi yokufaka nokukhishwa kwezinti, futhi inomsebenzi wokuhlukanisa noma ukuxuba amasiginali amabili ahlukene phakathi nokudlulisa nokwamukela. I-RF duplexer iyithuluzi lokudlulisela isignali eqondiswa kabili endleleni eyodwa. Emasistimu okuxhumana erediyo noma e-radar, ama-duplexer awavumela ukuthi abelane ngothi olujwayelekile kuyilapho ehlukanisa umamukeli kumthumeli.
2.RF ama-microwave passive diplexer angaklanywa kusetshenziswa izakhi zamaseli noma izinto ezincane ze-plana.
I-3.I-Duplexer design isebenzisa izingxenye ezimaphakathi: Emklamo, izingxenye ze-passive zisetshenziselwa ukwakha i-band-pass, i-low-pass kanye nezihlungi zokudlula eziphezulu ze-duplexer. I-duplexer yakhiwe kusetshenziswa izihlungi zamabhendi ezimbili ezinezimpendulo zemvamisa ezihlukene kodwa ezinezici ezifanayo zokwamukela kanye nezindlela zokudlulisela. Imiqondo yokuklama yokuhlunga njenge-Chebyshev ingasetshenziselwa ukuhlukaniswa okungcono phakathi kwemizila ye-Tx ne-Rx yamasekhethi ayisisekelo.
Qaphela kui-duplexer:
1.Isetshenziselwa ukusebenza kubhendi yefrikhwensi esetshenziswa umamukeli nesidlulisi, kumele ikwazi ukuphatha amandla okukhiphayo wesidlulisi.
2.Umsindo wesidluliseli owenzeka kumafrikhwensi okwamukela kumele ucindezelwe ngokwanele futhi kufanele uklanywe ukuthi usebenze ngaphansi noma ngaphansi kwekhefu lesikhawu phakathi komthumeli nomamukeli.
3.Ukuhlukaniswa okwanele kunganikezwa ukuvimbela ukungezwani komzimba komamukeli.

Isamukeli somvikeli
Si Chuan Keenlion Microwave ukukhethwa okukhulu kwe-RF Duplexer ekucushweni kwe-narrowband kanye ne-broadband, emboza amaza asuka ku-0.5 kuya ku-50 GHz. Zenzelwe ukuphatha amandla okufaka ama-watts asuka ku-10 kuye kwangama-30 kusistimu yokudlulisa engu-50-ohm. Imiklamo ye-Microstrip noma ye-stripline isetshenziswa, futhi yenzelwe ukusebenza kahle kakhulu.
Singakwazi futhi ukwenza ngokwezifiso i-RF Duplexer ngokwezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
