I-RF Duplexer
I-cavity duplexer uhlobo olukhethekile lwe-duplexer olusetshenziswa ezinhlelweni zokuxhumana ezingenantambo ukuhlukanisa izimpawu ezidluliselwayo nezamukelwe endaweni yemvamisa. I-cavity duplexer yakhiwa yizimbobo ezimbili ezizwakalayo, ngayinye enesibopho sokuxhumana ohlangothini olulodwa.
Isimiso sokusebenza se-cavity duplexer sisekelwe ekukhetheni imvamisa, esebenzisa i-resonant cavity ethile ukuze idlulisele amasignali ngokukhetha ngaphakathi kwebanga lemvamisa. Ngokukhethekile, lapho isignali ithunyelwa ku-cavity duplexer, idluliselwa ku-resonant cavity ethile futhi ikhuliswe futhi idluliselwe ku-resonant frequency yaleyo cavity. Ngesikhathi esifanayo, isignali eyamukelwe ihlala kwenye i-resonant cavity futhi ngeke idluliselwe noma iphazanyiswe.

Inhlanganisela yesignali ye-RFTYT RF Hybrid Combiner kanye ne-Amplification
I-RF hybrid combiner, njengengxenye ebalulekile yezinhlelo zokuxhumana ezingenantambo kanye namadivayisi kagesi e-radar kanye namanye amadivayisi kagesi e-RF, isetshenziswe kabanzi. Umsebenzi wayo oyinhloko ukuhlanganisa amasignali e-RF okufakwayo nokukhipha amasignali amasha ahlanganisiwe. I-RF Hybrid Combiner inezici zokulahlekelwa okuphansi, igagasi elincane lokuma, ukuhlukaniswa okuphezulu, i-amplitude enhle kanye nebhalansi yesigaba, kanye nokufakwayo okuningi kanye nemiphumela.
I-RF Hybrid Combiner yikhono layo lokufinyelela ukuhlukaniswa phakathi kwezibonakaliso zokufaka. Lokhu kusho ukuthi izimpawu zokufaka ezimbili ngeke ziphazamisane. Lokhu kuhlukaniswa kubaluleke kakhulu ezinhlelweni zokuxhumana ezingenantambo kanye nama-RF power amplifiers, njengoba kungavimbela ngempumelelo ukuphazamiseka kwesignali kanye nokulahlekelwa amandla.

Ama-RFTYT Ama-Couplers e-PIM aphansi ahlanganisiwe noma avulekile
I-coupler ye-intermodulation ephansi iyithuluzi elisetshenziswa kabanzi ezinhlelweni zokuxhumana ezingenantambo ukunciphisa ukuphazamiseka kwe-intermodulation kumadivayisi angenantambo. Ukuphazanyiswa kwe-intermodulation kubhekisela esimweni lapho izimpawu eziningi zidlula ohlelweni olungeyona i-linear ngesikhathi esisodwa, okuholela ekubonakaleni kwezingxenye zemvamisa ezingekho eziphazamisa ezinye izingxenye zemvamisa, okuholela ekunciphiseni ukusebenza kwesistimu engenantambo.
Ezinhlelweni zokuxhumana ezingenantambo, ama-couplers aphansi phakathi kwe-modulation avame ukusetshenziselwa ukuhlukanisa isignali yamandla aphezulu yokufaka kusuka kusignali yokukhipha ukuze kuncishiswe ukuphazamiseka phakathi kwe-modulation.

Isixhumi se-RF (3dB, 10dB, 20dB, 30dB)
I-coupler iyidivayisi ye-RF microwave esetshenziswa kakhulu esetshenziselwa ukusabalalisa amasignali okufaka ngokulingana kuma-port amaningi okukhipha, kanye namasignali okukhipha avela ku-port ngayinye ane-amplitude nezigaba ezahlukene. Isetshenziswa kabanzi ezinhlelweni zokuxhumana ezingenantambo, izinhlelo ze-radar, imishini yokulinganisa i-microwave, kanye neminye imikhakha.
Ama-coupler angahlukaniswa ngezinhlobo ezimbili ngokwesakhiwo sawo: i-microstrip kanye ne-cavity. Ingaphakathi le-microstrip coupler lakhiwe kakhulu yinethiwekhi yokuxhumanisa eyakhiwe ngemigqa emibili ye-microstrip, kuyilapho ingaphakathi le-cavity coupler lakhiwe ngemicu emibili yensimbi.
