Yog tias koj tau siv RF (xov tooj cua zaus) kev sib txuas lus, tes hauj lwm cellular, lossis antenna systems, tej zaum koj yuav ntsib lub sij hawm LMR cable. Tab sis nws yog dab tsi tiag tiag thiab vim li cas nws thiaj siv dav heev? Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb LMR cable yog dab tsi, nws cov yam ntxwv tseem ceeb, thiab vim li cas nws thiaj yog qhov kev xaiv zoo tshaj plaws rau RF daim ntawv thov, thiab teb cov lus nug 'LMR cable yog dab tsi?'.
To taub LMR coaxial cable
LMR cable yog ib qho coaxial cable tsim los rau kev ua haujlwm siab, qis poob teeb liab kis tau zoo hauv RF daim ntawv thov. LMR cables yog tsim los ntawm Times Microwave Systems thiab muaj npe nrov rau lawv txoj kev tiv thaiv zoo heev, qis poob teeb liab, thiab ruaj khov, ua rau lawv zoo tagnrho rau kev sib txuas lus wireless GPS, Kev xaiv zoo tshaj plaws 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 kev tiv thaiv thiab dielectric cov ntaub ntawv kom ntseeg tau tias muaj kev ncaj ncees zoo dua. Lawv tuaj ntau qhov ntau thiab tsawg los xaiv, xws li LMR-195, LMR-240, LMR-400, thiab LMR-600, txhua tus tsim rau kev ua haujlwm fais fab 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. Kev poob qis ntawm lub teeb liab
Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm LMR cables nrog kev poob teeb liab tsawg yog lawv qhov kev txo qis thaum mus deb (kev poob teeb liab). Qhov no ua tiav los ntawm kev rwb thaiv tsev zoo dielectric thiab kev tiv thaiv, uas txo qhov poob zog thaum cov teeb liab hla cov cables.
2. Kev ua tau zoo heev ntawm kev tiv thaiv
Kev tsim cov xov hlau LMR muaj ntau txheej tiv thaiv, feem ntau suav nrog cov txhuas txheej tiv thaiv rau kev tiv thaiv EMI (electromagnetic cuam tshuam) thawj zaug. Kev tiv thaiv sab nraud ua rau muaj kev ruaj khov thiab txo qis kev cuam tshuam. Qhov kev tiv thaiv no ua kom muaj zog dua thiab meej dua, ua rau cov xov hlau LMR yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov RF rhiab heev.
3. Kev ruaj khov thiab huab cua tsis kam
Times Microwave Systems tsim cov xov hlau LMR, uas nws lub plhaub sab nraud ruaj khov yog ua los ntawm polyethylene (PE) lossis thermoplastic elastomer (TPE), ua rau nws tiv taus ultraviolet radiation, noo noo, thiab kub heev. Qee qhov sib txawv, xws li LMR-UF (Ultra Flex), muab kev ywj pheej ntxiv rau kev teeb tsa uas xav tau kev khoov thiab txav mus los ntau zaus.
4. Kev teeb tsa yooj yim thiab yooj yim
Piv nrog cov cables coaxial rigid ib txwm muaj, LMR cables muaj kev ywj pheej siab thiab lub teeb yuag, ua rau kev teeb tsa yooj yim dua. Lawv lub vojvoog khoov yog me dua li ntawm cov cables RF zoo sib xws, uas tso cai rau kev teeb tsa nruj hauv qhov chaw kaw.
5. Kev sib raug zoo nrog cov khoom sib txuas RF
Cov xov hlau LMR txhawb nqa ntau lub connectors, suav nrog N-type connectors (feem ntau siv rau hauv antenna 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.
Cov Kev Siv Dav Dav ntawm LMR Cables
Ua tsaug rau nws qhov kev ua tau zoo heev, LMR cables tau siv dav hauv kev lag luam uas vam khom kev sib txuas lus RF. Qee qhov kev siv feem ntau suav nrog wireless thiab cellular networks, antenna thiab RF systems, GPS thiab satellite kev sib txuas lus, aerospace applications, kev saib xyuas thiab kev ruaj ntseg systems.
Xaiv cov LMR cable kom raug
Kev xaiv hom LMR cable kom raug nyob ntawm ntau yam, suav nrog zaus, qhov deb, kev tswj fais fab, thiab tej yam ib puag ncig. Nov yog qee qhov kev xaiv uas feem ntau siv:
LMR-195 thiab LMR-240: Haum rau cov ntawv thov luv luv xws li Wi Fi antennas thiab GPS systems.
LMR-400: Ib qho kev xaiv qis qis nruab nrab uas feem ntau siv rau hauv xov tooj ntawm tes thiab ob txoj kev xov tooj cua.
LMR-600: Zoo heev rau cov ntawv thov kev deb uas qhov teeb liab poob yuav tsum tau txo qis.
Yog tias koj xav tau qhov yooj ywm ntawm cov ntawv thov mobile, LMR-UF (Ultra Flex) cable kuj yog qhov kev xaiv zoo.
