Kodi RF circulator ndi chiyani ndipo RF isolator ndi chiyani?

Kodi chozungulira cha RF n'chiyani?

RF circulator ndi njira yotumizira ma branch yokhala ndi makhalidwe osagwirizana. Ferrite RF circulator imapangidwa ndi kapangidwe ka pakati kooneka ngati Y, monga momwe chithunzichi chikusonyezera. Imapangidwa ndi mizere itatu ya nthambi yogawidwa mofanana pa ngodya ya 120 ° kwa wina ndi mnzake. Pamene mphamvu ya maginito yakunja ili zero, ferrite simakhala ndi maginito, kotero mphamvu ya maginito mbali zonse imakhala yofanana. Pamene chizindikiro chikulowetsedwa kuchokera ku terminal 1, mphamvu ya maginito monga momwe zasonyezedwera mu chithunzi cha magnetic characteristic diagram idzasangalatsidwa pa malo olumikizirana ma ferrite, ndipo chizindikirocho chidzatumizidwa ku zotuluka kuchokera ku terminal 2. Mofananamo, chizindikiro cholowera kuchokera ku terminal 2 chidzatumizidwa ku terminal 3, ndipo chizindikiro cholowera kuchokera ku terminal 3 chidzatumizidwa ku terminal 1. Chifukwa cha ntchito yake ya chizindikiro choyendera ma cycle, chimatchedwa RF circulator.

Kugwiritsa ntchito kwachizolowezi kwa circulator: antenna yodziwika bwino yotumizira ndi kulandira zizindikiro
