1. Ukuhlunga i-Bandpass
I-diplexer ngokuvamile inezihlungi ezimbili ze-bandpass: eyodwa yebhendi yemvamisa yokudlulisa (Tx) (isb., 435-455MHz) kanye nenye yebhendi yemvamisa yokwamukela (Rx) (isb., 460-480MHz). Lezi zihlungi ze-bandpass zivumela amasignali ngaphakathi kwebanga lawo lemvamisa ukuthi adlule ngenkathi kunciphisa amasignali ngaphandle kwala ma-band. Lokhu kuhlukanisa ngempumelelo amasignali okudlulisa nokwamukela, kuvimbele ukuphazamiseka phakathi kwawo. Isibonelo, i-diplexer ingafinyelela ukuhlukaniswa okungu-30 dB noma ngaphezulu phakathi kwama-port ayo aphansi naphezulu, okwanele ezinhlelweni eziningi.

2. Umklamo Wokuhlukaniswa Okuphezulu
Izihlungi ze-cavity zivame ukusetshenziswa kuma-cavity diplexers ngenxa ye-Q factor yazo ephezulu kanye nokukhetha okuhle kakhulu. Lezi zihlungi zinikeza ukuhlukaniswa okuphezulu phakathi kwama-frequency band amabili, kunciphisa ukuvuza kwesignali kusuka ku-transmit band kuya ku-receive band kanye nokuphambene nalokho. Ukuhlukaniswa okuphezulu kunciphisa ingozi yokuphazamiseka phakathi kwesignali yokudlulisa neyokwamukela, kuqinisekisa ukusebenza okuzinzile kohlelo lokuxhumana. Eminye imiklamo ye-diplexer, njenge-high-receiving cavity duplexers, ingafinyelela amazinga aphezulu kakhulu okuhlukaniswa. Isibonelo, i-high-receiving cavity diplexer inganikeza amazinga okuhlukaniswa angu-80 dB noma ngaphezulu, icindezele ngempumelelo ukuphazamiseka.

3. Ukufaniswa kwe-Impedance
I-diplexer ifaka amanethiwekhi okufanisa i-impedance ukuqinisekisa ukufanisa okuhle kwe-impedance phakathi kweziteshi zokudlulisa nokwamukela kanye ne-antenna noma umugqa wokudlulisela. Ukufanisa kahle kwe-impedance kunciphisa ukubonakaliswa kwesignali namagagasi amile, ngaleyo ndlela kunciphisa ukuphazamiseka okubangelwa yizibonakaliso eziboniswayo. Isibonelo, i-common junction ye-diplexer iklanyelwe ukufeza ukufanisa okuhle kwe-impedance, ukuqinisekisa ukuthi i-input impedance ku-transmit frequency ingu-50 ohms ngenkathi iveza i-impedance ephezulu ku-receiver frequency.

4. Ukuhlukaniswa Kwesikhala
Ezinhlelweni zokuxhumana ezisebenza ndawonye, ​​ama-diplexer angahlanganiswa namanye amasu afana nokuqondisa kwe-antenna, ukunqamula ukuvuleka, kanye nokudlulisa imisebe ukuze kufezwe ukucindezelwa okwengeziwe kokuphazamiseka kwesignali endaweni yokusabalala. Isibonelo, ukusebenzisa ama-antenna aqondisayo kanye nama-diplexer kungathuthukisa ukuhlukaniswa phakathi kwama-antenna adlulisa kanye nawamukelayo, kuncishiswe amathuba okuphazamiseka kokubili.

5. Isakhiwo Esincane
Ama-diplexer e-cavity anesakhiwo esincane, esivumela ukuthi ahlanganiswe nama-antenna noma ezinye izingxenye. Lokhu kuhlanganiswa kunciphisa usayizi wesistimu iyonke kanye nobunzima ngenkathi kunciphisa izingozi zokuphazamiseka. Isibonelo, eminye imiklamo ye-diplexer ifaka amakhono okuhlunga endaweni evamile, okwenza isakhiwo sibe lula ngenkathi igcina ukusebenza okuphezulu.

II-Cavity Diplexer engu-435-455MHz/460-480MHzisebenzisa ukuhlunga kwe-bandpass, ukwakheka kokuhlukaniswa okuphezulu, ukufaniswa kwe-impedance, ukuhlukaniswa kwesikhala, kanye nobunye ubuchwepheshe ukuze iphathe ngempumelelo ukuphazamiseka kwesignali ezinhlelweni ze-LMR. Lokhu kuqinisekisa ukuthi izimpawu zokudlulisa nokwamukela zisebenza ngokuzimela ngaphandle kokuphazamiseka okuhambisanayo, okuthuthukisa ukuthembeka nokuzinza kwezinhlelo zokuxhumana.
