Dab tsi yog qhov txawv ntawm circulators thiab isolators?

Nyob rau hauv high-frequency circuits (RF/microwave, zaus 3kHz-300GHz),CirculatorthiabIsolatoryog qhov tseem ceeb passive non-reciprocal li, dav siv rau cov teeb liab tswj thiab kev tiv thaiv cov cuab yeej.

Qhov sib txawv ntawm cov qauv thiab cov teeb liab txoj kev

Circulator

Feem ntau yog peb-chaw nres nkoj (los yog ntau qhov chaw nres nkoj) ntaus ntawv, lub teeb liab yog cov tswv yim los ntawm ib qho chaw nres nkoj thiab cov zis nyob rau hauv ib qho kev taw qhia ruaj (xws li 1 → 2 → 3 → 1)

Isolator

Yeej ib qho khoom siv ob-chaw nres nkoj, nws tuaj yeem suav tias yog txuas ib kawg ntawm peb-chaw nres nkojlub circulatormus rau qhov sib txuam load kom ua tiav unidirectional teeb liab cais
Tsuas yog tso cai rau lub teeb liab dhau los ntawm kev tawm tswv yim rau cov zis, tiv thaiv lub teeb liab rov qab los, thiab tiv thaiv cov khoom siv.

Parameter thiab kev ua haujlwm sib piv

Tus naj npawb ntawm cov chaw nres nkoj: 3 ports for ua circulators, 2 ports raucais tawm

Teeb liab taw qhia:cov circulatorsyog circulated;cais tawmyog unidirectional

Isolation kev ua tau zoo:cais tawmfeem ntau muaj kev sib cais ntau dua thiab tsom rau kev thaiv cov cim rov qab

Daim ntawv thov qauv:cov circulatorsmuaj ntau cov qauv thiab cov nqi siab dua,cais tawmyog ntau compact thiab siv tau ntau dua

Daim ntawv thov scenarios

Circulator: Siv rau radar, kav hlau txais xov, kev sib txuas lus satellite thiab lwm yam xwm txheej kom ua tiav cov haujlwm xws li xa / txais kev sib cais thiab teeb liab hloov.

Isolator: Feem ntau siv nyob rau hauv lub hwj chim amplifiers, oscillators, xeem platforms, thiab lwm yam. los tiv thaiv cov cuab yeej los ntawm kev puas tsuaj los ntawm kev cuam tshuam cov teeb liab.
