XHUMANA MANJE

I-waveguide loop coupler iyidivayisi ye-microwave ehlanganisa i-loop waveguide kanye nemigqa yokudlulisela emibili.

Le coupler ye-microwave single directional loop coupler isetshenziselwa ikakhulukazi i-bandpass filteloop nokumatanisa kwe-short-circuit impedance kwemigqa yokudlulisela. Le coupler ingadlulisa amandla emvamisa ephezulu isuka kolayini wokudlulisela iye komunye, ngaleyo ndlela izuze ukuhlanganisa i-beam.

Umgomo wokusebenza we-waveguide loop coupler ngokuyinhloko uncike ezicini ezimbili: izici zokudlulisela ze-loop coupler nolayini we-microstrip.I-coupler eqondile isho isihlukanisi samandla esinokuqondisa.

I-loop coupler iyingxenye ebalulekile kuma-waveguide loop coupler, edlala indima enkulu ekuhlanganiseni amandla.

Lokhu kuhlangana kwe-annular kuqukethe amaluphu amabili asondelene, aneluphu eyodwa enguhhafu esebenza njengembobo yokufaka kanye nenye iluphu eyingxenye esebenza njengembobo yokuphumayo. Uma isignali yefrikhwensi ephezulu ifinyelela ekuhlanganisweni konyaka eduze kwembobo yokufaka, izodluliselwa kuluphu ewuhhafu eseduze. Kuleli qophelo, ngenxa yokuba khona kwensimu kazibuthe, isignali izophinde idluliselwe kwenye i-loop eyingxenye, ngaleyo ndlela kuzuzwe ukuhlanganisa amandla. Ekugcineni, kuyenzeka ukubhangqa isiginali yokokufaka ukusuka embobeni yokufaka kuya embobeni yokukhiphayo kuyilapho uhlanganisa izinga eliphezulu lokuhlanganisa ukusebenza kahle.

Izinkomba zokusebenza eziyinhloko ze-broadband single directional loop couplers

Izinkomba zokusebenza eziyinhloko zama-couplers e-measuloop zifaka ububanzi befrikhwensi yokusebenza, idigri yokuhlanganisa (noma ukuncishiswa koshintsho), inkombandlela, kanye nesilinganiso segagasi sokuma okokufaka/okukhiphayo.
1. Idigri yokuhlanganisa isho isilinganiso sedecibel samandla okokufaka we-waveguide eyinhloko kumandla okukhiphayo wembobo yokuhlanganisa ngaphansi kwesimo somthwalo ofanayo embotsheni ngayinye.
2. Isiqondiso sibhekisela esilinganisweni se-decibel samandla okukhiphayo wembobo ehlanganisayo kumandla okukhiphayo wembobo yokuhlukanisa ngaphansi kwesimo somthwalo ofanayo kumbobo ngayinye. Ama-coupler aqondisayo asetshenziswa kakhulu ukwenza amasampula esignali ekusabalaliseni amandla kanye nesilinganiso se-microwave.

Qualwaveihlinzeka nge-broadband namandla aphezulu ama-coupleal loop aqondisayo okukodwa ebangeni elibanzi ukusuka ku-2.6 kuye ku-18GHz. Ama-couplers asetshenziswa kabanzi ezinhlelweni eziningi.
