1. Ukuhluza iBandpass
I-diplexer ngokuqhelekileyo inezihluzo ezimbini ze-bandpass: enye ye-transmit (Tx) ibhendi yefrikhwensi (umz., 435-455MHz) kunye nenye ibhendi yokufumana (Rx) (umz., 460-480MHz). Ezi zihluzo ze-bandpass zivumela imiqondiso phakathi koluhlu lwazo lwamaxesha ukuba adlule ngelixa unciphisa imiqondiso ngaphandle kwezi bhanti. Oku kukwahlula ngokufanelekileyo ukuhanjiswa kunye nokufumana imiqondiso, ukuthintela ukuphazamiseka phakathi kwabo. Umzekelo, i-diplexer inokufikelela kukwahlulwa kwe-30 dB okanye ngaphezulu phakathi kwamazibuko ayo aphantsi naphakamileyo, anele kwizicelo ezininzi.

2. Uyilo oluphezulu lokuzahlula
Izihluzi ze-Cavity ziqhele ukusetyenziswa kwi-cavity diplexers ngenxa ye-Q factor ephezulu kunye nokukhetha okugqwesileyo. Ezi zihluzo zibonelela ngokuzikhethela okuphezulu phakathi kweebhendi zamaza ezibini, ukunciphisa ukuvuza komqondiso ukusuka kwibhendi yokuhambisa ukuya kwibhendi yokufumana kwaye ngokuphambeneyo. Ukuzihlukanisa okuphezulu kunciphisa umngcipheko wokuphazamiseka phakathi kokudlulisa kunye nokufumana iimpawu, ukuqinisekisa ukusebenza kwenkqubo yonxibelelwano oluzinzile. Olunye uyilo lwe-diplexer, olunje nge-high-rejection cavity duplexers, lunokufikelela kumanqanaba aphezulu kakhulu okuba wedwa. Ngokomzekelo, i-diplexer ye-high-rejection cavity inokubonelela ngamanqanaba okuzihlukanisa angama-80 dB okanye ngaphezulu, ukucinezela ngokufanelekileyo ukuphazamiseka.

3. I-Impedans Matching
I-diplexer ibandakanya uthungelwano oluhambelanayo lwe-impedance ukuqinisekisa ukuhambelana okuhle kokuthintela phakathi kokuhambisa kunye nokwamkela iziteshi kunye ne-antenna okanye umgca wothumelo. Ukulinganisa okufanelekileyo kwe-impedance kunciphisa ukubonakaliswa komqondiso kunye namaza amileyo, ngaloo ndlela kuncitshiswe ukuphazamiseka okubangelwa yimiqondiso ebonakalisiweyo. Umzekelo, isiphambuka esiqhelekileyo se-diplexer siyilelwe ukufezekisa ukuhambelana okugqwesileyo kwe-impedance, iqinisekisa ukuba igalelo lokungena kwi-frequency transmit frequency yi-50 ohms ngelixa inikezela nge-impedance ephezulu kumaza okufumana.

4. Ukwahlulwa kwesithuba
Kwiinkqubo zonxibelelwano lwendawo edibeneyo, i-diplexers inokudityaniswa kunye nobunye ubuchule obunje nge-antenna directionality, cross-polarization, kunye nokuhambisa i-beamforming ukuphumeza ukucinezelwa ngakumbi kokuphazamiseka komqondiso kwisizinda sosasazo. Umzekelo, ukusebenzisa i-eriyali ezalathisayo ngokudityaniswa ne-diplexer kunokonyusa ukwahlula phakathi kokuhambisa kunye nokufumana ii-eriyali, ukunciphisa ukubakho kokuphazamiseka okufanayo.

5. Ulwakhiwo olubambeneyo
I-Cavity diplexers ibonisa isakhiwo esidibeneyo, esivumela ukuba zidibaniswe nee-antenna okanye ezinye izinto. Oku kudityaniswa kunciphisa ubungakanani benkqubo yonke kunye nobunzima ngelixa kunciphisa umngcipheko wokuphazamiseka. Umzekelo, uyilo oluthile lwe-diplexer lubandakanya amandla okucoca kumdibaniso oqhelekileyo, ukwenza lula ulwakhiwo ngelixa ugcina ukusebenza okuphezulu.

I435-455MHz/460-480MHz Cavity Diplexerisebenzisa ukuhluzwa kwe-bandpass, uyilo oluphezulu lokuzahlula, ukuhambelana kokumelana, ukwahlula indawo, kunye nobunye ubuchwepheshe bokuphatha ngokufanelekileyo ukuphazamiseka komqondiso kwiinkqubo ze-LMR. Oku kuqinisekisa ukuba ukuhanjiswa kunye nokufumana iimpawu zisebenza ngokuzimeleyo ngaphandle kokuphazamiseka okufanayo, ukuphucula ukuthembeka kunye nokuzinza kweenkqubo zonxibelelwano.
