1800-2000MHZ UHF Band RF Coaxial Isolator
Isolator yog dab tsi?
RF cais tawmyog ib tug dual chaw nres nkoj ferromagnetic passive ntaus ntawv, uas yog siv los tiv thaiv lwm yam RF Cheebtsam los ntawm kev puas tsuaj los ntawm cov teeb liab muaj zog heev xav txog. Isolators muaj nyob rau hauv cov ntawv thov kev sim thiab tuaj yeem cais cov cuab yeej hauv kev sim (DUT) los ntawm cov teeb liab rhiab heev.
Daim ntawv thov khoom
• Laboratory xeem (ultra bandwidth)
• Kev sib txuas lus satellite
• Wireless system

Qhov txawv ntawm isolator thiab circulator
Lub circulator yog ib qho khoom siv ntau qhov chaw nres nkoj uas xa cov xwm txheej nthwv dej nkag mus rau txhua qhov chaw nres nkoj mus rau qhov chaw nres nkoj tom ntej raws li cov kev taw qhia tau txiav txim los ntawm qhov sib txawv ntawm qhov sib nqus sib nqus. Lub ntsiab feature yog lub unidirectional kis tau tus mob ntawm lub zog, uas tswj cov kis tau tus mob ntawm electromagnetic nthwv dej raws li ib ncig txoj kev.
Piv txwv li, nyob rau hauv lub circulator nyob rau hauv daim duab hauv qab no, lub teeb liab yuav tsuas yog los ntawm qhov chaw nres nkoj 1 mus rau qhov chaw nres nkoj 2, los ntawm qhov chaw nres nkoj 2 mus rau qhov chaw nres nkoj 3, thiab los ntawm qhov chaw nres nkoj 3 mus rau qhov chaw nres nkoj 1, thiab lwm yam txoj kev yog thaiv (kev sib cais siab).
Lub isolator feem ntau yog raws li cov qauv ntawm lub circulator. Qhov sib txawv tsuas yog tias tus cais tawm feem ntau yog ob qhov chaw nres nkoj, uas txuas peb qhov chaw nres nkoj ntawm lub voj voog mus rau qhov sib txuam load lossis kuaj xyuas Circuit Court. Yog li, xws li kev ua haujlwm yog tsim: lub teeb liab tsuas tuaj yeem mus ntawm qhov chaw nres nkoj 1 mus rau qhov chaw nres nkoj 2, tab sis tsis tuaj yeem rov qab mus rau qhov chaw nres nkoj 1 los ntawm qhov chaw nres nkoj 2, uas yog, ib txoj kev txuas mus ntxiv yog pom tau.
Yog tias 3-chaw nres nkoj txuas nrog lub ntsuas ntsuas, qhov tsis sib haum xeeb ntawm cov khoom siv davhlau ya nyob twg raug txiav los ntawm 2-chaw nres nkoj kuj tuaj yeem pom tau, thiab kev saib xyuas yoj sawv ntsug tuaj yeem pom tau.
