Mfundo ndi Kugwiritsa Ntchito kwa Madoko Atatu a Circulator mu Microwave System

Madoko atatuCirculatorndi chipangizo chofunikira cha microwave/RF, chomwe chimagwiritsidwa ntchito kwambiri poyendetsa ma signal, kudzipatula komanso poyendetsa ma duplex. Nkhaniyi ikufotokoza mwachidule mfundo zake za kapangidwe kake, makhalidwe ake ndi momwe amagwiritsidwira ntchito.

Kodi madoko atatu ndi chiyani?chozungulira?

Madoko atatuchozungulirandi chipangizo chopanda ntchito, chosagwirizana ndi madoko atatu, ndipo chizindikirocho chimangoyendayenda pakati pa madoko mbali imodzi yokha:

Kulowetsa kuchokera ku doko 1 → kutulutsa kuchokera ku doko 2 lokha;

Kulowetsa kuchokera ku doko 2 → kutulutsa kuchokera ku doko 3 lokha;

Kulowetsa kuchokera ku doko 3 → kutulutsa kuchokera ku doko 1 lokha.

Mwabwino kwambiri, kutumiza chizindikiro cha madoko atatuchozunguliraikutsatira njira yokhazikika: doko 1 → doko 2, doko 2 → doko 3, doko 3 → doko 1, kupanga njira yozungulira yolunjika. Doko lililonse limatumiza zizindikiro ku doko lotsatira lokha, ndipo chizindikirocho sichidzatumizidwa mobwerera mmbuyo kapena kutuluka kupita ku madoko ena. Khalidweli limatchedwa "kusabwezerana". Khalidwe labwino kwambiri lotumizira lingathe kufotokozedwa ndi matrix wamba yofalikira, zomwe zikusonyeza kuti ili ndi kutayika kochepa kwa kulowetsa, kudzipatula kwakukulu, komanso magwiridwe antchito otumizira.

Mapulogalamu Odziwika

Kugwiritsa Ntchito Isolator: Kawirikawiri imagwiritsidwa ntchito m'makina a microwave amphamvu kwambiri kuti ateteze ma transmitter ku kuwonongeka kwa mafunde owonetsedwa. Doko lachitatu limalumikizidwa ndi katundu wofanana kuti lipeze kusungulumwa kwakukulu.

Ntchito ya Duplexer: Mu radar kapena machitidwe olumikizirana, imagwiritsidwa ntchito kuti ma transmitter ndi olandila azitha kugawana antenna imodzi popanda kusokonezana.

Dongosolo Lokulitsa Mphamvu Yowunikira: Pophatikizidwa ndi zipangizo zotsutsa mphamvu (monga ma Gunn diode), ma circulator angagwiritsidwe ntchito kupatula njira zolowera ndi zotuluka.
