Chotsukira cha Dual Junction 700-1000Mhz LDGL-0.7/1-S

Cholumikizira cha ma microwave cholumikizira ma dual junction chokhala ndi cholumikizira cha SMA ndi mtundu wa microwave yomwe imagwiritsidwa ntchito kupereka padera pakati pa magawo osiyanasiyana a circuit, makamaka mu ma frequency apamwamba kuyambira 700 mpaka 1000 MHz. Chipangizochi chimagwira ntchito yofunika kwambiri popewa kuwunikira kwa ma signal ndi kusokoneza, motero kumawonjezera magwiridwe antchito onse a ma microwave.

Cholumikizira cha dual junction chimakhala ndi zinthu ziwiri za ferrite zolekanitsidwa ndi ma spacers osagwiritsa ntchito maginito, zomwe zili mkati mwa chivundikiro chachitsulo chomwe chili ndi zolumikizira za SMA (SubMiniature version A) kuti zigwirizane mosavuta ndi ma microwave circuits. Cholumikizira cha SMA ndi mtundu wodziwika bwino wa cholumikizira cha coaxial RF, chodziwika chifukwa cha kulimba kwake komanso kudalirika kwake pakugwiritsa ntchito ma frequency apamwamba. Cholumikizira chimagwira ntchito kutengera mfundo ya magnetic biasing, komwe mphamvu ya maginito ya direct current (DC) imagwiritsidwa ntchito molunjika kunjira ya RF signal flow.

Mu ma frequency awa a 700 mpaka 1000 MHz, chodzipatula chimatseka bwino ma signal omwe akuyenda mbali imodzi pomwe amalola ma signal kudutsa mbali ina. Kapangidwe kameneka kamathandiza kuteteza zinthu zobisika ku kuwonongeka komwe kumachitika chifukwa cha mphamvu yowunikira kapena ma signal osafunikira obwerera, omwe nthawi zambiri amapezeka mumakina otumizira ndi olandila. Kuphatikiza apo, kumathandizira kukhazikika kwa ma oscillator mwa kuyamwa mphamvu iliyonse yowunikira, kuchepetsa zotsatira zokoka pafupipafupi.

Ma Dual Junction isolators amapereka milingo yokwera yodzipatula kuposa ma single junction isolators, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito zinthu zovuta zomwe zimafuna umphumphu wabwino wa chizindikiro. Amagwiritsidwa ntchito kwambiri mu machitidwe olumikizirana, ukadaulo wa radar, kulumikizana ndi satellite, ndi ntchito zina zosiyanasiyana za microwave komwe umphumphu wa chizindikiro ndi kukhazikika kwa dongosolo ndizofunikira kwambiri.

Mwachidule, cholumikizira cha dual junction chokhala ndi cholumikizira cha SMA, chopangidwira ma frequency kuyambira 700 mpaka 1000 MHz, ndi gawo lofunikira kwambiri muukadaulo wa microwave. Chimapereka kudzipatula kwabwino kwambiri, chimaletsa kuwunikira kwa chizindikiro, komanso chimasunga magwiridwe antchito onse a dongosolo poonetsetsa kuti zizindikiro zikuyenda molunjika komwe zikufuna.
