Fyuluta ya Band Pass

Cholumikizira cha cavity duplexer ndi mtundu wapadera wa cholumikizira cha duplexer chomwe chimagwiritsidwa ntchito mumakina olumikizirana opanda zingwe kuti chilekanitse zizindikiro zotumizidwa ndi zolandiridwa mu gawo la ma frequency. Cholumikizira cha cavity duplexer chimakhala ndi ma resonant cavities awiri, omwe ali ndi udindo wolumikizana mbali imodzi.

Mfundo yogwirira ntchito ya cavity duplexer imachokera pa kusankha ma frequency, komwe kumagwiritsa ntchito cavity yeniyeni ya resonant kuti itumize ma signal mosankha mkati mwa ma frequency range. Makamaka, chizindikiro chikatumizidwa mu cavity duplexer, chimatumizidwa ku cavity inayake ya resonant ndipo chimakulitsidwa ndikutumizidwa pa resonant frequency ya cavity imeneyo. Nthawi yomweyo, chizindikiro cholandiridwacho chimakhalabe mu cavity ina ya resonant ndipo sichidzatumizidwa kapena kusokonezedwa nacho.

Kapangidwe kake kamapezeka mukapempha.

Zigawo ziwiri zazikulu za duplexer ya cavity ndi cavity yotumizira ndi cavity yolandirira.

Kutalikirana kwakukulu, kutayika kochepa kwa malo olowera, kudalirika, komanso kukhazikika kwa ma diplexer otsekeka m'mimba kumawapatsa ubwino waukulu mu makina olumikizirana opanda zingwe.

Ma diplex a cavity amagwira ntchito yofunika kwambiri mu makina olumikizirana opanda zingwe, makamaka oyenera zochitika zomwe kutumiza ndi kulandira zizindikiro kumafunika kuti zikhale pamodzi mu bandeji imodzi ya ma frequency. Mwachitsanzo, kulumikizana pakati pa malo oyambira ndi zida zam'manja, kulumikizana pakati pa malo olumikizirana opanda zingwe ndi zida zowunikira, ndi zina zotero. Pogwiritsa ntchito ma diplex a cavity, makinawa amatha kupeza kulumikizana kogwira mtima komanso kodalirika kwa mbali ziwiri.
