Isimiso kanye Nokusetshenziswa Kwesiyingi Sezimbobo Ezi-3 Kuhlelo Lwe-Microwave

Izimbobo ezi-3I-circulatoriyidivayisi ebalulekile ye-microwave/RF, evame ukusetshenziswa ekuqondiseni amasignali, ekuhlukaniseni kanye nasezimweni ezimbili. Lesi sihloko sethula kafushane isimiso sayo sokwakheka, izici zokusebenza kanye nezinhlelo zokusebenza ezijwayelekile.

Iyini i-3-porti-circulator?

I-port engu-3i-circulatoriyidivayisi yamachweba amathathu engenzi lutho, engashintshisani, futhi isignali ingajikeleza kuphela phakathi kwamachweba ngendlela eqondile:

Okokufaka okuvela echwebeni 1 → okukhiphayo okuvela echwebeni 2 kuphela;

Okokufaka okuvela echwebeni 2 → okukhiphayo okuvela echwebeni 3 kuphela;

Okokufaka okuvela echwebeni 3 → okukhiphayo okuvela echwebeni 1 kuphela.

Okungcono kakhulu, ukudluliswa kwesignali kwe-3-porti-circulatorilandela isiqondiso esinqunyiwe: ichweba 1 → ichweba 2, ichweba 2 → ichweba 3, ichweba 3 → ichweba 1, yakha indlela ye-loop eqondiswe ngakunye. Ichweba ngalinye lidlulisela amasignali kuphela echwebeni elilandelayo, futhi isignali ngeke idluliselwe emuva noma ivuthwe kwamanye amachweba. Lesi sici sibizwa ngokuthi "ukungaphindiseli". Lokhu kuziphatha okuhle kokudlulisela kungachazwa nge-standard scattering matrix, okubonisa ukuthi inokulahlekelwa okuphansi kokufakwa, ukuhlukaniswa okuphezulu, kanye nokusebenza kokudlulisela okuqondisiwe.

Izinhlobo Zesakhiwo

I-Coaxial, Ukungena ngemvume, Ukukhweza Okungaphezulu, I-Microstrip, futhiUmhlahlandlela wamagagasiizinhlobo

Izicelo Ezijwayelekile

Ukusetshenziswa Kwe-Isolator: Ivame ukusetshenziswa ezinhlelweni ze-microwave ezinamandla aphezulu ukuvikela ama-transmitter ekulimaleni kwamagagasi abonakalayo. Imbobo yesithathu ixhunywe kumthwalo ofanayo ukuze kufezwe ukuhlukaniswa okuphezulu.

Umsebenzi we-Duplexer: Ezinhlelweni ze-radar noma zokuxhumana, isetshenziselwa ukuthi abathumeli kanye nabamukeli babelane nge-antenna efanayo ngaphandle kokuphazamisana.

Uhlelo Lokukhulisa Ukukhanya: Kuhlanganiswe namadivayisi okumelana nokungalungi (njenge-Gunn diodes), ama-circulator angasetshenziswa ukuhlukanisa izindlela zokufaka nezokukhipha.
