I-Dual Junction Isolator 700-1000Mhz LDGL-0.7/1-S

Isihlukanisi se-dual junction esinesixhumi se-SMA wuhlobo lwengxenye ye-microwave esetshenziselwa ukuhlinzeka ngokuhlukaniswa phakathi kwezigaba ezihlukene zesekhethi, ikakhulukazi ezinhlelweni zokusebenza zemvamisa ephezulu ukusuka ku-700 kuye ku-1000 MHz. Le divayisi idlala indima ebalulekile ekuvimbeleni ukubonakaliswa kwesignali kanye nokuphazamiseka, ngaleyo ndlela ithuthukise ukusebenza okuphelele kwamasistimu e-microwave.

Isihlukanisi se-dual junction siqukethe izinto ezimbili ze-ferrite ezihlukaniswa izikhala ezingezona uzibuthe, ezivalelwe ngaphakathi kwekesi lensimbi elinezixhumi ze-SMA (SubMiniature version A) ukuze zihlanganiswe kalula kumasekhethi e-microwave. Isixhumi se-SMA siwuhlobo oluvamile lwesixhumi se-coaxial RF, esaziwa ngokuqina nokwethembeka ezinhlelweni ezisebenza ngamaza aphezulu. I-isolator isebenza ngokususelwe kumgomo wokuchema kazibuthe, lapho inkambu kazibuthe yamanje (DC) isetshenziswa ngokuqondile lapho kugeleza khona isignali ye-RF.

Kulolu hlu lwefrikhwensi engu-700 kuye ku-1000 MHz, isihlukanisi sivimba ngempumelelo amasiginali ahamba ngendlela eyodwa kuyilapho sivumela amasignali ukuthi adlulele kwelinye icala. Lesi sakhiwo esingaqondile sisiza ukuvikela izingxenye ezizwelayo emonakalweni obangelwa amandla abonisiwe noma amasiginali angafuneki ahlehlayo, avame ukubonakala ezinhlelweni zesidlulisi nomamukeli. Ngaphezu kwalokho, ithuthukisa ukuzinza kwama-oscillator ngokumunca noma yimaphi amandla abonisiwe, inciphise imiphumela yokudonsa imvamisa.

Izihlukanisi ze-Dual junction zinikeza amazinga aphezulu okuzihlukanisa kunezihlukanisi ze-Junction eyodwa, okuzenza zilungele izinhlelo zokusebenza ezidingeka kakhulu ezidinga ubuqotho besignali engcono. Asetshenziswa kakhulu ezinhlelweni zokuxhumana ngocingo, ubuchwepheshe be-radar, ezokuxhumana ngesathelayithi, nezinye izinhlelo zokusebenza ezihlukene zama-microwave lapho ubuqotho besignali nokuzinza kwesistimu kubaluleke kakhulu.

Kafushane, isihlukanisi se-dual junction nesixhumi se-SMA, esidizayinelwe amafrikhwensi ukusuka ku-700 kuya ku-1000 MHz, siyingxenye ebalulekile kubunjiniyela be-microwave. Ihlinzeka ngokuhlukaniswa okuhle kakhulu, ivimbele ukuboniswa kwesignali, futhi igcine ukusebenza kwesistimu iyonke ngokuqinisekisa ukuthi amasiginali ahamba kuphela ngendlela ehlosiwe.
