I-cavity duplexer wuhlobo olukhethekile lwe-duplexer olusetshenziswa ezinhlelweni zokuxhumana ezingenantambo ukuhlukanisa amasiginali adlulisiwe nawamukelwe esizindeni samafrikhwensi.I-cavity duplexer iqukethe imigodi emibili enomsindo, ngayinye inesibopho sokuxhumana ohlangothini olulodwa.
Umgomo wokusebenza we-cavity duplexer usekelwe ekukhetheni imvamisa, esebenzisa i-resonant cavity ethile ukuze ukhethe ngokukhetha amasignali ngaphakathi kwebanga lemvamisa.Ikakhulukazi, lapho isignali ithunyelwa ku-cavity duplexer, idluliselwa endaweni ethize ene-resonant futhi ikhuliswe futhi idluliselwe kwimvamisa yokukhala kwaleyo ndawo.Ngesikhathi esifanayo, isignali etholiwe ihlala kwesinye i-resonant cavity futhi ngeke idluliselwe noma iphazamiseke.
