Coaxial Cable qee zaum hu ua RF Cable lossis RF Coaxial Cable. Coaxial RF Cable yog cov qauv siv feem ntau. Vim hais tias cov khoom siv sab hauv thiab sab nraud muaj nyob rau hauv qhov chaw siab, lub tshuab hluav taws xob muaj lub zog tawm mus rau qhov nruab nrab ntawm qhov nruab nrab ntawm sab nraud thiab sab nraud cov cuab yeej, yog li nws muaj qhov zoo tseem ceeb xws li tsis muaj attenuation, siab tiv thaiv kev ua tau zoo, kev siv bandwidth thiab ruaj khov. Feem ntau siv los xa cov xov tooj cua ntau lub zog los ntawm 500 kHz mus rau 18 GHz. Ib coaxial cable muaj ob lub concentric conductors, thiab tus neeg xyuas pib thiab ntaub thaiv npog sib thooj ntawm tib lub cable. Cov xov tooj coaxial ntau tshaj muaj cov tooj liab neeg xyuas pib cais los ntawm cov khoom siv insulating. Sab nraud ntawm cov khoom siv sab hauv insulating yog lwm txheej ntawm cov nplhaib neeg xyuas pib thiab nws cov rwb thaiv tsev, thiab tom qab ntawd tag nrho cov xov yog them los ntawm polyvinyl chloride lossis Teflon cov khoom siv hnab riam. Coaxial cable tuaj yeem faib ua 50Ω baseband cable thiab 75Ω broadband cable xov tooj cua zaus coaxial cable. Baseband cables tau muab faib ua nyias coaxial cables thiab tuab coaxial cables. Txoj hlua khi loj yog tsuas yog siv rau kev xa cov digital, thiab cov ntaub ntawv tus tuaj yeem ncav cuag 10Mbps. Cov yam ntxwv ntawm tus cwj pwm tsis txaus 50Ω xov tooj cua zaus coaxial cable feem ntau yog siv rau lub teeb liab bandband, qhov kis tau tus mob yog 1-20MHz, thiab tus yam ntxwv tsis cuam tshuam 75Ω xov tooj cua zaus coaxial cable feem ntau siv hauv CATV network, yog li nws hu ua CATV cable, thiab kis tau tus mob bandwidth tuaj yeem ncav cuag 1GHz. Qhov xa xov bandwidth yog 750MHz.
RG179 coaxial cable
RG179 coaxial cable ua raws li tus qauv: M17 / 94-RG179, kev ua haujlwm siab tshaj plaws: DC-3GHz, cov hluav taws xob zoo hluav taws xob cuam tshuam thiab hloov tau yooj yim, tsis tsuas yog lub teeb hauv qhov hnyav, tab sis kuj muaj cov yam ntxwv ntawm qhov kub tsis kam, tiv thaiv ya raws, corrosion kuj , kev tiv thaiv, ua kom pom tseeb, Lub nthwv dej sawv ntsug thiab lwm yam taw qhia tau zoo ua hluav taws xob. Nws yog dav siv hauv kev sib txuas lus, kev tsav dav hlau, cov neeg txawj ntse, cov tub rog thiab lwm qhov.
