RFTYT Cavity Diplexer Kuphatikiza kapena Open Circuit

A cavity duplexer ndi mtundu wapadera wa duplexer womwe umagwiritsidwa ntchito pamakina olumikizirana opanda zingwe kuti alekanitse ma siginecha opatsiridwa ndi olandilidwa mumayendedwe pafupipafupi.The cavity duplexer imakhala ndi mikwingwirima iwiri, iliyonse imayang'anira kulumikizana mbali imodzi.

Mfundo yogwirira ntchito ya pabowo duplexer imatengera kusankha pafupipafupi, komwe kumagwiritsa ntchito kabowo kakang'ono kake kuti atumize ma siginecha mkati mwa ma frequency osiyanasiyana.Mwachindunji, pamene chizindikiro amatumizidwa mu patsekeke duplexer, izo zimafalitsidwa kwa enieni resonant patsekeke ndi amakuza ndi opatsirana pa resonant pafupipafupi pabowo kuti.Panthawi imodzimodziyo, chizindikiro cholandilidwa chimakhalabe muzitsulo zina zomveka ndipo sichidzafalikira kapena kusokonezedwa.

Zigawo ziwiri zazikulu za cavity duplexer ndi khomo lopatsirana ndi khomo lolandirira.

Kudzipatula kwakukulu, kutayika pang'ono, kudalirika, ndi kukhazikika kwa ma diplexer amkati kumawapatsa mwayi waukulu pamakina olumikizirana opanda zingwe.

Ma Cavity diplexers amatenga gawo lofunikira pamakina olumikizirana opanda zingwe, makamaka oyenera pazochitika zomwe kutumiza ndi kulandira ma siginecha amafunikira kuti azikhala mu band ya ma frequency omwewo.Mwachitsanzo, kulumikizana pakati pa masiteshoni oyambira ndi zida zam'manja, kulumikizana pakati pa masiteshoni opanda zingwe ndi zida zowunikira, ndi zina zambiri. Pogwiritsa ntchito ma diplexers am'mimba, dongosololi limatha kulumikizana bwino komanso lodalirika la bidirectional.
