Mfundo ndi Kugwiritsa Ntchito 3-Port Circulator mu Microwave System

3-PortWozungulirandi chipangizo chofunikira cha microwave/RF, chomwe chimagwiritsidwa ntchito kwambiri popanga ma siginoloji, kudzipatula komanso kuchita zinthu ziwiri. Nkhaniyi ikufotokoza mwachidule mfundo zake, machitidwe ake komanso momwe amagwiritsidwira ntchito.

Kodi 3-port ndi chiyaniwozungulira?

A 3-dokowozungulirandi chipangizo cha madoko atatu, chosasinthasintha, ndipo chizindikirocho chimangozungulira pakati pa madoko molunjika:

Zolowetsa kuchokera ku doko 1 → zotuluka kuchokera padoko 2;

Zolowetsa kuchokera ku doko 2 → zotuluka kuchokera padoko 3;

Zolowetsa kuchokera ku doko 3 → zotuluka kuchokera padoko 1.

Momwemo, kutumizira ma siginecha a 3-dokowozunguliraimatsatira njira yokhazikika: doko 1 → doko 2, doko 2 → doko 3, doko 3 → doko 1, kupanga njira yolumikizirana yosagwirizana. Doko lililonse limatumiza zidziwitso ku doko lotsatira, ndipo chizindikirocho sichidzaperekedwa mobwerera kapena kutayikira kumadoko ena. Makhalidwe amenewa amatchedwa "non-reciprocity". Mchitidwe wopatsirana wabwinowu ukhoza kufotokozedwa ndi matrix wobalalika wokhazikika, kuwonetsa kuti ili ndi kutayika kocheperako, kudzipatula kwambiri, komanso kufalikira kolowera.

Ntchito Zofananira

Kugwiritsa Ntchito Isolator: Nthawi zambiri amagwiritsidwa ntchito m'makina amphamvu kwambiri a microwave kuteteza ma transmit ku kuwonongeka kwa mafunde. Doko lachitatu limalumikizidwa ndi katundu wofananira kuti akwaniritse kudzipatula kwakukulu.

Ntchito ya Duplexer: Mu radar kapena machitidwe olumikizirana, amagwiritsidwa ntchito kuti ma transmitters ndi olandila agawane mlongoti womwewo popanda kusokonezana.

Reflection Amplifier System: Kuphatikizidwa ndi zida zotsutsa (monga ma diode a Gunn), zozungulira zitha kugwiritsidwa ntchito kupatula njira zolowera ndi zotulutsa.
