RF connectors, tseem hu ua coaxial connectors, pab xa cov cim RF los ntawm kev sib txuas cov kab xa mus rau ntau yam kev siv. RF connectors feem ntau yog siv nrog coaxial cables. Koj yuav pom lawv siv hauv TV receivers, ob-txoj kev xov tooj cua, Wi-Fi li nrog cov kav hlau txais xov, thiab cov cuab yeej ntsuas kev lag luam thiab kev tshawb fawb. Hauv tsab xov xwm no, peb yuav hais txog qee qhov kev sib txuas ntau tshaj plaws, suav nrog:BNC, SMA, SMB, N-hom, thiab TNC.
RF connectors me me, tab sis tuaj yeem muab kev siv ntau dua rau coaxial cables. Lawv yuav tsum tau ua kom haum cov kev qhia tshwj xeeb ntawm coaxial cable txhawm rau txhawm rau xa cov teeb liab dhau los ntawm nws. Yog li ntawd, kev paub dav dav ntawm coaxial cable connectors tuaj yeem ua ke thaum tsim kev cai cable sib dhos (los yog thaum thov kev cai sib dhos los ntawm cov chaw tsim khoom). Peb tau ua tiav cov kev tshawb fawb thiab sau cov ntaub ntawv tseem ceeb tshaj plaws rau koj hauv qhov kev tshaj tawm blog no.
Dab tsi yog coaxial cable?
Txhawm rau kom nkag siab zoo dua li cas RF connectors ua haujlwm, peb yuav tsum xub nkag siab tias coaxial cables ua haujlwm li cas. Txhawm rau xa xov tooj cua zaus los ntawm point A mus rau point B, peb yuav tsum siv cov kab sib kis. Coaxial cable yog txoj kab sib txuas ntawm kev xaiv vim nws khaws cov teeb liab kis ntawm cov khoom sab hauv thiab sab nraud. Qhov no txhais tau hais tias coaxial cables muaj teeb liab tsawg dua thiab tuaj yeem muab tso rau ib sab ntawm cov khoom hlau yam tsis muaj kev cuam tshuam.
Daim duab hauv qab no qhia tau hais tias coaxial cable muaj xws li: lub hauv paus tseem ceeb (tus neeg xyuas pib), lub dielectric insulator, ib daim hlau thaiv (sab nrauv) thiab lub tsho. Qhov chaw nruab nrab ntawm sab hauv thiab sab nraud yog qhov impedance. Qhov kev ntsuas no tseem ceeb rau kev ua haujlwm ntawm coaxial cable. Lub impedance yuav tsum yog tib yam nyob rau tag nrho ntev ntawm lub cable los yog lub teeb liab yuav tshwm sim. Thaum RF connectors muab tso rau ntawm qhov kawg ntawm ib coaxial cable, lub impedances yuav tsum sib phim. Txwv tsis pub, lub teeb liab tsis tuaj yeem kis tau zoo.
Hom hom RF connectors
Tsim kom zoo RF connectors thaiv cov teeb liab sab nraud ntawm lub voj voog thiab tiv thaiv kom tsis muaj zog. Cov connectors muaj built-in fastening mechanisms xws li threads, bayonets, brackets, los yog dig muag plugs. Cov tsis tseem ceeb uas yuav tsum xav txog suav nrog: impedance, ntau zaus, kev tuav fais fab, qhov loj me thiab tus nqi.
