Isivikelo se-Waveguide
I-waveguide isolator iyithuluzi elingasebenzi elisetshenziswa kuma-RF kanye nama-frequency band e-microwave ukuze kufezwe ukudluliselwa okuqondile kanye nokuhlukaniswa kwezibonakaliso. Inezici zokulahlekelwa okuphansi kokufakwa, ukuhlukaniswa okuphezulu, kanye ne-broadband, futhi isetshenziswa kabanzi ekuxhumaneni, e-radar, e-antenna nakwezinye izinhlelo. Isakhiwo esiyisisekelo se-waveguide isolator sihlanganisa imigqa yokudlulisela i-waveguide kanye nezinto ezisebenza ngomagnetic. Intambo yokudlulisela i-waveguide iyipayipi lensimbi elingenalutho lapho kudluliswa khona izimpawu. Izinto ezisebenza ngomagnetic ngokuvamile ziyizinto ezisetshenziswayo ze-ferrite ezibekwa ezindaweni ezithile emigqeni yokudlulisela i-waveguide ukuze kufezwe ukuhlukaniswa kwezibonakaliso. I-waveguide isolator ihlanganisa nezingxenye ezisizayo ezimunca umthwalo ukuze kuthuthukiswe ukusebenza futhi kuncishiswe ukubonakaliswa.
Ibanga lemvamisa lisukela ku-5.4 kuya ku-110GHz.
Izinhlelo zokusebenza zezempi, zesikhala nezentengiselwano.
Ukulahlekelwa okuphansi kokufakwa, ukuhlukaniswa okuphezulu, ukuphathwa kwamandla aphezulu.
Idizayini eyenziwe ngokwezifiso iyatholakala uma iceliwe.

Umphikisi Oholelekile
Ama-Resistors ane-Lead, aziwa nangokuthi ama-resistors amabili e-SMD, angenye yezingxenye ezisetshenziswa kakhulu kumasekethe kagesi, anomsebenzi wokulinganisa amasekethe. Afeza ukusebenza okuzinzile kwesekethe ngokulungisa inani lokumelana kwisekethe ukuze kufezwe isimo esilinganiselwe samanje noma i-voltage. Adlala indima ebalulekile kumadivayisi kagesi nezinhlelo zokuxhumana. I-resistors ene-lead iwuhlobo lwe-resistor engenama-flange engeziwe, evame ukufakwa ngqo ebhodini lesekethe ngokushisela noma ukufaka. Uma kuqhathaniswa nama-resistors ane-flange, ayidingi ukulungiswa okukhethekile kanye nezakhiwo zokusabalalisa ukushisa.

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.
