I-dual direction hybrid coupler series

I-Directional coupler wuhlobo lwedivayisi ye-microwave esetshenziswa kabanzi ohlelweni lwe-microwave.Ingqikithi yayo iwukusabalalisa amandla esignali ye-microwave ngengxenye ethile.

Ama-coupler aqondiswayo akhiwe izintambo zokudlulisela.Imigqa yama-coaxial, ama-waveguides angama-rectangular, ama-waveguides ayindilinga, imigqa ehlutshiwe kanye nemigqa emincane konke kungakha ama-couplers aqondisayo.Ngakho-ke, ngokombono wesakhiwo, ama-couplers aqondisayo anezinhlobonhlobo zezinhlobo kanye nomehluko omkhulu.Kodwa-ke, ngokombono wendlela yayo yokuhlanganisa, ingahlukaniswa ngezinhlobo ezine, okungukuthi, ukuhlanganisa iphinifa, ukuhlanganisa okuhambisanayo, ukuhlanganisa i-branching nokumatanisa i-T ephindwe kabili.

I-coupler eqondisayo iyingxenye ebeka imigqa yokudlulisela emibili eduze ngokwanele ukuze amandla akulayini owodwa ahlanganiswe namandla komunye.I-amplitude yesiginali yezimbobo zayo ezimbili zokuphuma ingalingana noma ingalingani.I-coupler esetshenziswa kakhulu yi-3dB coupler, futhi ukuphakama kwamasiginali okukhiphayo wezimbobo zayo ezimbili zokuphuma kuyalingana.

I-coupler eyisiqondiso isici sokuhlanganisa amandla esiqondiso (ukusabalalisa).Iyingxenye yamachweba amane, ngokuvamile akhiwa imigqa yokudlulisela emibili ebizwa ngokuthi umugqa oqondile (umugqa oyinhloko) nolayini wokuhlanganisa (umugqa wesibili).Ingxenye (noma yonke) yamandla olayini oqondile ihlanganiswe nomugqa wokuhlanganisa ngokusebenzisa indlela ethile yokuhlanganisa (njengezikhala, izimbobo, izingxenye zomugqa ohlanganisayo, njll.) phakathi komugqa oqondile nolayini wokuhlanganisa, futhi amandla idingeka ukuthi idluliselwe embobeni yokukhipha eyodwa kuphela emugqeni wokuhlanganisa, kuyilapho enye imbobo ingenawo amandla aphumayo.Uma isiqondisindlela sokusakazeka kwegagasi emugqeni oqondile siba ngokuphambene nendawo yasekuqaleni, imbobo yokukhipha amandla kanye nembobo engeyona amandla okukhipha emugqeni wokuxhumanisa nakho kuzoshintsha ngokufanele, okungukuthi, ukuhlanganisa amandla (ukusabalalisa) kuyaqondisa, ngakho-ke ebizwa ngokuthi i-directional coupler (i-directional coupler).

Njengengxenye ebalulekile yamasekethe amaningi e-microwave, ama-couplers aqondisayo asetshenziswa kakhulu ezinhlelweni zesimanje zikagesi.Ingasetshenziselwa ukunikeza amandla esampula esinxephezelo sezinga lokushisa kanye namasekhethi okulawula i-amplitude, futhi ingaqedela ukusatshalaliswa kwamandla kanye nokuhlanganisa ebangeni elibanzi lokuvama;Ku-amplifier elinganisiwe, kuyasiza ukuthola isilinganiso esihle se-voltage stand wave ratio (VSWR);Kumshini wokuhlanganisa olinganiselayo kanye nemishini ye-microwave (isb, i-network analyzer), ingasetshenziswa ukusampula isigameko kanye namasignali abonisiwe;Ekuxhumaneni kweselula, sebenzisa.

I-coupler yebhuloho engu-90 ° inganquma iphutha lesigaba sesithumeli sikakhiye wokushintsha kwesigaba (QPSK) esingu-π/4.I-coupler ifaniswe nesici sokuvimbela kuzo zonke izimbobo ezine, okwenza kube lula ukushumeka kwamanye amasekethe noma amasistimu angaphansi.Ngokusebenzisa izakhiwo zokuhlanganisa ezihlukene, izindlela zokuhlanganisa nezindlela zokuhlanganisa, ama-couplers aqondisayo afanele izidingo ezahlukene zamasistimu e-microwave ahlukahlukene angaklanywa.
