1800-2000MHZ UHF Band RF Coaxial Isolator
Kodi wodzipatula ndi chiyani?
RF isolatorndi chipangizo chapawiri cha ferromagnetic passive, chomwe chimagwiritsidwa ntchito kuteteza zida zina za RF kuti zisaonongeke ndi kunyezimira kwamphamvu kwambiri. Zodzipatula ndizofala m'ma labotale ndipo zimatha kulekanitsa zida zomwe zikuyesedwa (DUT) ndi magwero ozindikira.
Kugwiritsa ntchito mankhwala
• Kuyesa kwa laboratory (ultra bandwidth)
• Kulankhulana kwa satellite
• Makina opanda zingwe

Kujambula autilaini
Kusiyana pakati pa isolator ndi circulator
Chozungulira ndi chipangizo cha madoko ambiri chomwe chimatumiza mafunde a zochitika kulowa pa doko lina lililonse molingana ndi momwe maginito amayendera. Chodziwika kwambiri ndi kutumizirana mphamvu kwapang'onopang'ono, komwe kumayang'anira kufalikira kwa mafunde a electromagnetic mozungulira mozungulira.
Mwachitsanzo, mu circulator mu chithunzi pansipa, chizindikiro chikhoza kukhala kuchokera ku doko 1 kupita ku doko 2, kuchokera ku doko 2 kupita ku doko 3, ndi kuchokera ku doko 3 kupita ku doko 1, ndi njira zina zotsekedwa (kudzipatula kwakukulu)
Wodzipatula nthawi zambiri amatengera kapangidwe ka circulator. Chosiyana chokha ndikuti chodzipatula nthawi zambiri chimakhala chipangizo cha doko ziwiri, chomwe chimagwirizanitsa madoko atatu a circulator ndi katundu wofanana kapena dera lodziwika. Chifukwa chake, ntchito yotereyi imapangidwa: chizindikirocho chimangopita ku doko 1 kupita ku doko 2, koma sichingabwerere ku doko 1 kuchokera ku doko 2, ndiko kuti, kupitiriza kwa njira imodzi kumatheka.
Ngati doko la 3-lolumikizidwa ndi chowunikira, kusagwirizana kwa chipangizocho komwe kuthetsedwa ndi doko la 2 kumathanso kuzindikirika, ndipo ntchito yowunikira yoyimirira imatha kuzindikirika.
