I-1800-2000MHZ UHF Band RF Coaxial Isolator
Kuyini i-isolator?
Isihlukanisi se-RFiyidivayisi ye-ferromagnetic passive enezimbobo ezimbili, esetshenziselwa ukuvikela ezinye izingxenye ze-RF ekulimaleni ngenxa yokubonakaliswa kwesignali okunamandla kakhulu. Ama-isolator avamile ezicelweni zelebhu futhi angahlukanisa imishini evivinywayo (i-DUT) nemithombo yesignali ebucayi.
Isicelo somkhiqizo
• Ukuhlolwa kwelebhu (i-bandwidth ephezulu)
• Ukuxhumana ngesathelayithi
• Uhlelo olungenantambo

Umdwebo Wohlaka
Umehluko phakathi kwe-isolator ne-circulator
I-circulator iyithuluzi elinamachweba amaningi elidlulisela igagasi lesigameko lingena kunoma yiliphi ichweba liye kwelinye ichweba ngokuya ngesiqondiso esinqunywe yinsimu yamagnetic ye-static bias. Isici esivelele ukudluliselwa kwamandla ngendlela eyodwa, okulawula ukudluliselwa kwamagagasi kagesi ngendlela eyindilinga.
Isibonelo, ku-circulator esithombeni esingezansi, isignali ingaba kuphela kusukela ku-port 1 kuya ku-port 2, kusukela ku-port 2 kuya ku-port 3, kanye nokusuka ku-port 3 kuya ku-port 1, kanti ezinye izindlela zivaliwe (ukuhlukaniswa okuphezulu)
I-isolator ngokuvamile isekelwe esakhiweni se-circulator. Umehluko kuphela ukuthi i-isolator ivame ukuba yidivayisi yamachweba amabili, exhumanisa amachweba amathathu e-circulator kumjikelezo womthwalo noma wokuthola ofanayo. Ngakho-ke, umsebenzi onjalo uyakhiwa: isignali ingahamba kuphela kusuka ku-port 1 kuya ku-port 2, kodwa ayikwazi ukubuyela ku-port 1 kusuka ku-port 2, okungukuthi, ukuqhubeka kwendlela eyodwa kuyafezeka.
Uma i-3-port ixhunywe kumtholi, izinga lokungafani kwedivayisi yokugcina eqedwe yi-2-port lingabonakala, futhi umsebenzi wokuqapha amagagasi amile ungabonakala.
