1800-2000MHZ UHF Band RF Coaxial Isolator
Yintoni isihlukanisi?
I-RF isolatorsisixhobo esisebenza ekukhuseleni amanye amalungu eRF ekonakalisweni kukubonakalisa isignali eyomeleleyo. I-Isolators zixhaphakile kwizicelo zaselabhoratri kwaye zinokohlula izixhobo eziphantsi kovavanyo (DUT) kwimithombo yemiqondiso ebuthathaka.
Isicelo semveliso
• Uvavanyo lwaselabhoratri (i-ultra bandwidth)
• Unxibelelwano ngesathelayithi
• Inkqubo engenazingcingo

Umahluko phakathi kwe-isolator kunye ne-circulator
Umjikijelo sisixhobo sezibuko ezininzi esihambisa iliza lesehlo lingena nakweliphi na izibuko kwizibuko elilandelayo ngokolwalathiso olumiselwe ngumhlaba wemagnethi othambekele omileyo. Olona phawu lubalaseleyo kukuhanjiswa kwamandla ngendlela enye, elawula ukuhanjiswa kwamaza ombane we-electromagnetic kwicala lesetyhula.
Ngokomzekelo, kwi-circulator kumfanekiso ongezantsi, isibonakaliso sinokuvela kuphela kwi-port 1 ukuya kwi-port 2, ukusuka kwi-port 2 ukuya kwi-port 3, kwaye ukusuka kwi-port 3 ukuya kwi-port 1, kunye nezinye iindlela zivaliwe (ukuhlukaniswa okuphezulu)
I-isolator ngokuqhelekileyo isekelwe kwisakhiwo se-circulator. Ukwahlukana kuphela kukuba i-isolator idla ngokuba sisixhobo se-port ezimbini, esidibanisa izibuko ezintathu ze-circulator kumthwalo ohambelanayo okanye ukufumanisa isiphaluka. Ngaloo ndlela, umsebenzi onjalo wenziwa: isibonakaliso sinokuhamba kuphela kwi-port 1 ukuya kwi-port 2, kodwa ayikwazi ukubuyela kwi-port 1 ukusuka kwi-port 2, oko kukuthi, ukuqhubeka kwendlela enye kuyenzeka.
Ukuba i-3-port iqhagamshelwe kwi-detector, idigri engafanelekanga yesixhobo se-terminal esipheliswe yi-2-port nayo inokuqondwa, kwaye umsebenzi wokujonga amaza omileyo unokufezekiswa.
