1800-2000MHZ UHF Band RF Coaxial Isolator
Kodi chodzipatula n'chiyani?
Cholekanitsa cha RFndi chipangizo chopanda mphamvu cha ferromagnetic chokhala ndi ma port awiri, chomwe chimagwiritsidwa ntchito kuteteza zigawo zina za RF kuti zisawonongeke ndi kuwunikira kwamphamvu kwambiri kwa chizindikiro. Zosiyanitsa zimakhala zofala kwambiri mu ntchito za labotale ndipo zimatha kulekanitsa zida zomwe zikuyesedwa (DUT) ndi magwero a chizindikiro chodziwika bwino.
Kugwiritsa ntchito mankhwala
• Kuyesa kwa labotale (bandwidth ya ultra)
• Kulankhulana kwa satellite
• Makina opanda zingwe

Chojambula cha Ndondomeko
Kusiyana pakati pa isolator ndi circulator
Circulator ndi chipangizo chokhala ndi madoko ambiri chomwe chimatumiza mafunde olowera mu doko lililonse kupita ku doko lotsatira malinga ndi njira yomwe imatsimikiziridwa ndi mphamvu yamagetsi ya static bias. Chinthu chachikulu ndi kutumiza mphamvu molunjika, komwe kumalamulira kutumiza kwa mafunde amagetsi mozungulira.
Mwachitsanzo, mu circulator yomwe ili pachithunzi chili pansipa, chizindikirocho chingakhale kuchokera ku doko 1 kupita ku doko 2, kuchokera ku doko 2 kupita ku doko 3, komanso kuchokera ku doko 3 kupita ku doko 1, ndipo njira zina zatsekedwa (kupatula kwakukulu)
Chodzipatula nthawi zambiri chimadalira kapangidwe ka circulator. Kusiyana kokha ndichakuti chodzipatula nthawi zambiri chimakhala chipangizo chokhala ndi madoko awiri, chomwe chimalumikiza madoko atatu a circulator ku dera lofanana la katundu kapena lozindikira. Chifukwa chake, ntchito yotereyi imapangidwa: chizindikirocho chimangopita kuchokera ku doko 1 kupita ku doko 2, koma sichingabwerere ku doko 1 kuchokera ku doko 2, ndiko kuti, kupitiriza kwa njira imodzi kumachitika.
Ngati doko lachitatu lalumikizidwa ku chowunikira, digiri yosagwirizana ya chipangizo cha terminal chomwe chatsekedwa ndi doko lachiwiri ikhozanso kudziwika, ndipo ntchito yowunikira mafunde oyima ikhoza kudziwika.
