I-1800-2000MHZ UHF Band RF Coaxial Isolator
Yintoni i-isolator?
I-RF isolatorsisixhobo esisetyenziswa njenge-dual port ferromagnetic passive device, esisetyenziselwa ukukhusela ezinye izinto ze-RF ekubeni zonakaliswe kukubonakaliswa kwesignali okunamandla kakhulu. Ii-isolators zixhaphakile kwizicelo zelebhu kwaye zinokuhlula izixhobo ezivavanywayo (DUT) kwimithombo yesignali ebuthathaka.
Isicelo semveliso
• Uvavanyo lwelebhu (i-bandwidth ephezulu)
• Unxibelelwano lwesathelayithi
• Inkqubo engenazingcingo

Umzobo Wemida
Umahluko phakathi kwe-isolator kunye ne-circulator
I-circulator sisixhobo esinee-port ezininzi esithumela i-incident wave ingena nakweyiphi na i-port iye kwi-port elandelayo ngokwendlela echazwe yi-static bias magnetic field. Uphawu oluphambili kukudluliselwa kwamandla ngendlela enye, okulawula ukudluliselwa kwamaza e-electromagnetic kwicala elijikelezayo.
Umzekelo, kwi-circulator ekumfanekiso ongezantsi, isignali inokuvela kuphela kwizibuko 1 ukuya kwizibuko 2, ukusuka kwizibuko 2 ukuya kwizibuko 3, kunye nokusuka kwizibuko 3 ukuya kwizibuko 1, kwaye ezinye iindlela zivaliwe (ukuhlukaniswa okuphezulu)
I-isolator isekelwe kwisakhiwo se-circulator. Umahluko kuphela kukuba i-isolator idla ngokuba sisixhobo sezibuko ezimbini, esidibanisa iizibuko ezintathu ze-circulator kwisekethe yomthwalo okanye yokubona ehambelanayo. Ngoko ke, umsebenzi onjalo uyenziwa: isignali inokusuka kwizibuko 1 ukuya kwizibuko 2 kuphela, kodwa ayinakubuyela kwizibuko 1 ukusuka kwizibuko 2, oko kukuthi, ukuqhubeka kwendlela enye kuyafezekiswa.
Ukuba i-3-port iqhagamshelwe kwi-detector, inqanaba lokungafani kwesixhobo sesiphelo esipheliswe yi-2-port nalo linokuphunyezwa, kwaye umsebenzi wokujonga amaza amiyo unokuphunyezwa.
