Chipangizo Chosagwiritsa Ntchito cha RF Cirulator

2. Kapangidwe ka RF Cirulator

Mfundo ya chipangizo cha RF Circulator ndikusankha mphamvu ya anisotropic ya zinthu za ferrite ndi mphamvu ya maginito. Pogwiritsa ntchito mphamvu ya Faraday rotation ya ndege ya polarization yomwe imazungulira pamene mafunde a electromagnetic amatumizidwa mu ferrite yozungulira yokhala ndi mphamvu ya DC yakunja ya maginito, ndipo kudzera mu kapangidwe koyenera, ndege ya polarization ya mafunde a electromagnetic imakhala yolunjika ku pulagi yokhazikika yotsutsa panthawi yotumizira patsogolo, zomwe zimapangitsa kuti pakhale kuchepa pang'ono. Mu transmission yobwerera m'mbuyo, ndege ya polarization ya mafunde a electromagnetic imafanana ndi pulagi yokhazikika yotsutsa ndipo imayamwa pafupifupi kwathunthu. Kapangidwe ka microwave kamaphatikizapo microstrip, waveguide, strip line, ndi coaxial types, pakati pawo microstrip three terminal circulators ndi omwe amagwiritsidwa ntchito kwambiri. Zipangizo za Ferrite zimagwiritsidwa ntchito ngati medium, ndipo kapangidwe ka conduction band kamayikidwa pamwamba, ndi mphamvu ya maginito yokhazikika yowonjezeredwa, kuti akwaniritse mawonekedwe a circulator. Ngati njira ya bias magnetic field yasinthidwa, njira ya loop idzasintha.

Chithunzi chotsatirachi chikuwonetsa kapangidwe ka chipangizo choyimitsidwa pamwamba, chokhala ndi kondakitala wapakati (CC), ferrite (FE), mbale yamaginito yofanana (PO), maginito (MG), mbale yochepetsera kutentha (TC), chivindikiro (Lid), ndi thupi.
