Yog tias koj tau siv RF (xov tooj cua zaus) kev sib txuas lus, xov tooj ntawm tes, lossis kav hlau txais xov, koj tuaj yeem ntsib lo lus LMR cable. Tab sis qhov tseeb yog dab tsi thiab yog vim li cas nws thiaj li siv dav? Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov LMR cable yog dab tsi, nws cov yam ntxwv tseem ceeb, thiab vim li cas nws thiaj li yog qhov kev xaiv zoo tshaj plaws rau kev siv RF, thiab teb cov lus nug 'LMR cable yog dab tsi?'.
Nkag siab LMR coaxial cable
LMR cable yog coaxial cable tsim los rau kev ua haujlwm siab, tsis tshua muaj teeb liab kis tau tus mob hauv RF daim ntaub ntawv. LMR cables yog tsim los ntawm Times Microwave Systems thiab muaj npe nrov rau lawv cov kev tiv thaiv zoo heev, tsis tshua muaj teeb liab poob, thiab ua haujlwm ntev, ua rau lawv zoo tagnrho rau kev sib txuas lus wireless GPS, Zoo tagnrho xaiv rau radar thiab lwm yam RF raws li systems. Tsis zoo li cov coaxial cables ib txwm muaj, LMR cables yog tsim los nrog ntau txheej ntawm cov ntaub thaiv npog thiab cov khoom siv dielectric kom ntseeg tau tias cov teeb liab zoo dua. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg los xaiv los ntawm, xws li LMR-195, LMR-240, LMR-400, thiab LMR-600, txhua tus tsim los rau kev ua haujlwm sib txawv thiab cov teeb liab poob.
Cov yam ntxwv tseem ceeb ntawm LMR coaxial cable
LMR cables sawv tawm hauv thaj chaw ntawm coaxial cables vim lawv cov qauv tshwj xeeb thiab kev ua tau zoo:
1. Tsawg teeb liab poob
Ib qho ntawm qhov zoo tshaj plaws ntawm LMR cables uas tsis tshua muaj teeb liab poob yog lawv qhov qis qis dua nyob rau qhov ntev (lub teeb liab poob). Qhov no yog ua tiav los ntawm cov khoom zoo dielectric rwb thaiv tsev thiab shielding, uas txo lub zog poob thaum cov teeb liab dhau los ntawm cables.
2. Kev tiv thaiv zoo heev
LMR cable tsim muaj ntau txheej tiv thaiv, feem ntau suav nrog txhuas sawb shielding rau thawj EMI (electromagnetic cuam tshuam) tiv thaiv. Weaving sab nraud shielding txhim khu durability thiab ntxiv txo kev cuam tshuam. Qhov kev tiv thaiv no ua kom muaj zog dua thiab pom tseeb, ua rau LMR cables yog qhov kev xaiv zoo tshaj plaws rau kev siv RF rhiab heev.
3. Durability thiab huab cua tsis kam
Lub Sijhawm Microwave Systems tsim LMR cables, uas nws cov tawv tawv sab nrauv yog ua los ntawm polyethylene (PE) lossis thermoplastic elastomer (TPE), ua rau nws tiv taus hluav taws xob ultraviolet, noo noo, thiab kub heev. Qee qhov sib txawv, xws li LMR-UF (Ultra Flex), muab kev yooj yim ntxiv rau kev teeb tsa uas yuav tsum tau khoov thiab txav mus.
4. Yooj yim thiab yooj yim installation
Piv nrog cov tsoos nruj coaxial cables, LMR cables muaj qhov yooj yim thiab hnav, ua kom yooj yim dua. Lawv lub vojvoog dabtsi yog khoov me dua li qhov zoo sib xws ntawm RF cables, uas tso cai rau kev teeb tsa nruj hauv qhov chaw kaw.
5. Compatibility nrog RF connectors
LMR cables txhawb ntau qhov sib txuas, suav nrog N-hom txuas (feem ntau siv hauv cov kav hlau txais xov thiab RF daim ntawv thov). SMA connector (rau wireless thiab GPS systems). BNC connector (nrov hauv kev tshaj tawm thiab kev sib txuas lus). Qhov kev sib raug zoo no ua rau lawv muaj ntau yam hauv ntau yam lag luam.
Kev siv ntau yam ntawm LMR Cables
Ua tsaug rau nws cov kev ua tau zoo, LMR cables tau siv dav hauv kev lag luam uas tso siab rau kev sib txuas lus RF. Qee qhov kev siv ntau tshaj plaws suav nrog wireless thiab xov tooj ntawm tes, kav hlau txais xov thiab RF systems, GPS thiab satellite kev sib txuas lus, kev siv aerospace, kev saib xyuas thiab kev ruaj ntseg.
Xaiv qhov raug LMR cable
Kev xaiv ntawm LMR cable hom yog nyob ntawm ntau yam, suav nrog zaus, nyob deb, kev tuav fais fab, thiab ib puag ncig. Nov yog qee qhov kev xaiv ntau:
LMR-195 thiab LMR-240: Haum rau kev siv luv luv xws li Wi-nkaus kav hlau txais xov thiab GPS tshuab.
LMR-400: Ib qho kev poob qis qis nruab nrab feem ntau siv hauv xov tooj ntawm tes thiab ob txoj hauv kev xov tooj cua.
LMR-600: Zoo heev rau daim ntawv thov nyob deb qhov twg cov teeb liab poob yuav tsum raug txo kom tsawg.
Yog tias koj xav tau qhov hloov pauv ntawm cov ntawv thov txawb, LMR-UF (Ultra Flex) cable kuj yog qhov kev xaiv zoo.
