Chiphunzitso choyambirira cha RF circulator ndi RF isolator

Mu ukadaulo wa microwave, RF circulator ndi RF isolator ndi zida ziwiri zofunika kwambiri za ferrite zomwe zimagwiritsidwa ntchito makamaka poyang'anira ndi kusiyanitsa zizindikiro za microwave.
Khalidwe lalikulu la zipangizozi ndi kusasinthasintha kwawo, zomwe zikutanthauza kuti kutayika kwa chizindikiro kumakhala kochepa panthawi yotumiza uthenga kutsogolo, pomwe kumayamwa mphamvu zambiri panthawi yotumiza uthenga kumbuyo.
Khalidweli limatsimikiziridwa ndi kuyanjana pakati pa mphamvu ya maginito ndi ferrite ya microwave.
Mphamvu ya maginito imapereka maziko a kusabwezera, pomwe ferrite imatsimikiza kuchuluka kwa resonant kwa chipangizocho, ndiko kuti, momwe chimayankhira ku pafupipafupi inayake ya microwave.

Mfundo yogwira ntchito ya RF circulator ndikugwiritsa ntchito mphamvu ya maginito kuwongolera zizindikiro za microwave. Chizindikiro chikalowa kuchokera ku doko lina lolowera, chimatsogozedwa ku doko lina lotulutsira, pomwe kutumiza kobwerera kumakhala kotsekedwa.
Zosiyanitsa zimapita patsogolo pa izi, osati kungoletsa zizindikiro zobwerera m'mbuyo, komanso zimalekanitsa bwino njira ziwiri za zizindikiro kuti zisasokonezeke pakati pa zizindikiro.

Ndikofunikira kudziwa kuti ngati pali mphamvu yamaginito yokha popanda microwave ferrite, kutumiza kwa zizindikiro kudzakhala kofanana, ndiko kuti, zotsatira za kutumiza kwa kutsogolo ndi kumbuyo zidzakhala chimodzimodzi, zomwe sizikugwirizana ndi cholinga cha kapangidwe ka RF circulator ndi RF isolator. Chifukwa chake, kupezeka kwa ferrite ndikofunikira kwambiri kuti zipangizozi zigwire ntchito bwino.
