XHUMANA MANJE

I-Waveguide single directional crossguide coupler iqukethe amagagasi amabili ane-engeli yesokudla.

Ukuhlanganisa kufinyelelwa ngokuqala izimbobo ezimbili ezincane odongeni olubanzi oluvamile lwe-waveguide. Ngemuva komklamo wokulungiselela, amandla esignali ahlanganiswe kulezi zimbobo ezimbili zokuhlanganisa angahlehliswa futhi akhanselwe. Lezi zimbobo ngokuvamile zenziwe zibe imbobo encane yokuwela ukuze kuzuzwe ukusebenza kahle.

I-coupler eqondisayo iyingxenye ebeka imigqa yokudlulisela emibili eduze ukuze amandla kulayini owodwa ahlanganiswe komunye. I-coupler ifaniswe nesici esivimbelayo kuwo wonke amachweba amane, okwenza kube lula ukushumeka kwamanye amasekethe noma amasistimu angaphansi. Ngokwamukela izakhiwo zokuhlanganisa ezihlukene, imidiya yokuhlanganisa, nezindlela zokuhlanganisa, ama-couplers aqondisayo afanele amasistimu ama-microwave ahlukahlukene anezidingo ezahlukene angaklanywa.

Isicelo:

Ama-couplers aqondisayo, njengengxenye ebalulekile yamasekethe amaningi e-microwave, asetshenziswa kakhulu ezinhlelweni zesimanje zikagesi. Ingasetshenziselwa ukunikeza amandla okusampula esinxephezelo sezinga lokushisa namasekhethi okulawula i-amplitude, futhi ingaqedela ukwabiwa kwamandla kanye nokuhlanganiswa phezu kwebanga elibanzi lefrikhwensi.
1. Ku-amplifier elinganiselayo, isiza ukuzuza isilinganiso esihle se-voltage emi-wave ye-input-output (VSWR).
2. Kuma-mixer alinganiselayo namadivayisi we-microwave (njengabahlaziyi benethiwekhi), ingasetshenziswa ukwenza isampula yesigameko namasignali abonisiwe.
3. Ekuxhumaneni kweselula, ukusetshenziswa kwe-coupler yebhuloho elingu-90 ° kunganquma iphutha lesigaba sesidlulisi se-π/4 phase shift keying (QPSK).

Qualwaveihlinzeka nge-broadband namandla aphezulu ama-coupleal single directional crossguide couplers ebangeni elibanzi ukusuka ku-1.13 kuye ku-40GHz. Kunezinhlobo ezahlukahlukene zamachweba we-waveguide, njenge-WR-28 ne-WR-34. Ama-couplers asetshenziswa kabanzi ezinhlelweni eziningi.
Siyakwamukela amakhasimende ukuze ushayele futhi ubuze.
