Ukwabelana ngesithombe se-RFTYT sebhendi ye-UHF engu-400-470MHz NF RF Coaxial Cirulator

Umsebenzi oyinhloko we-RF coaxial circulator ukudlulisa amandla esignali ephezulu ngendlela eyodwa, futhi inezinhlelo zokusebenza ezinhle kumadivayisi anjenge-isolators, ama-duplexers, kanye nama-reflection amplifiers.
I-RF coaxial circulator iyithuluzi elinamachweba amaningi elingadlulisela igagasi lesigameko lingena kunoma yimaphi amachweba alo liye kwelinye ichweba ngendlela enqunywe yi-static bias magnetic field. Isici sayo esingenakukwazi yikhono layo lokudlulisa amandla esignali anemvamisa ephezulu ngendlela engeyona eyeyalo, okusebenza njengokuhlukaniswa phakathi kokukhishwa kwe-amplifier yamandla anemvamisa ephezulu kanye nomthwalo, okuvikela i-amplifier yamandla ezinguqukweni zokuphazamiseka komthwalo. Ngaphezu kwalokho, ama-RF coaxial circulators nawo adlala indima ekudlulisweni kwesignali eqondisayo kanye nokudluliselwa kanye nokwamukelwa kwe-duplex ohlelweni. Angasetshenziswa ezinhlelweni ze-radar/zokuxhumana ukuze ahlukanise izimpawu zokwamukela/zokudlulisa komunye nomunye, futhi ukudlulisa nokwamukela kungabelana nge-antenna efanayo. Lo mklamo awugcini nje ngokwenza lula isakhiwo sesistimu, kodwa futhi uthuthukisa ukuthembeka nokusebenza kahle kwesistimu.
Uhla lokusetshenziswa kwama-coaxial circulators lubanzi, kufaka phakathi kodwa kungagcini nje kwezombusazwe, ezempi, ezindiza, ubuchwepheshe besikhala kanye neminye imikhakha. Angamelana namandla aphezulu, abe nokulahlekelwa okuncane kokufakwa kanye nezici zokuhlukanisa eziphezulu, mancane ngobukhulu kodwa anamandla ekusebenzeni. Ngokushintsha isiqondiso sensimu ye-ferrite bias, isiqondiso sokuqhutshwa kwesignali singashintshwa, okwenza ama-coaxial circulators abe usizo kakhulu ezinhlelweni zokusebenza ezidinga ukucutshungulwa kwesignali okuguquguqukayo. Ngaphezu kwalokho, angasetshenziswa futhi njenge-isolators ukufeza ukuhlukaniswa phakathi kwezigaba, ukufaniswa kwe-impedance, ukudluliselwa kwesignali yamandla, kanye nokuvikelwa kohlelo lokuhlanganiswa kwamandla olungaphambili ngokuxhuma umthwalo ohambisanayo kwelinye ichweba le-circulator.
Ngamafuphi, i-RF coaxial circulator isibe yingxenye ebalulekile ezinhlelweni zesimanje ze-elekthronikhi ngenxa yokudluliselwa kwayo kwamandla esignali asebenza imvamisa ephezulu kanye nezinhlelo zokusebenza ezahlukahlukene ohlelweni, idlala indima ebalulekile ekuthuthukiseni ukusebenza kwesistimu kanye nokuthembeka.
