Kev piav qhia
Txoj kev rov qab lim dej yog siv los hla cov amplifiers hauv ib txwm coax raws li TV network ntawm cov ntaub ntawv zaus ntawm EoC. Qhov no tso cai rau cov ntaub ntawv kom muaj txoj hauv kev rov qab thiab TV teeb liab yuav tsum tau nthuav dav.

Nws tus kheej lub Hoobkas nyob hauv Shenzhen thiab muaj ntau tshaj 1000 tus neeg ua haujlwm. Nws yog lub tuam txhab ua haujlwm siab -tech enterprise integrating R&D, ntau lawm, muag thiab kev pabcuam, Lub tuam txhab tshwj xeeb hauv Kav hlau txais xov / Network Kev sib txuas lus / Bluetooth / AV Accessories / Smart Home / Car Accessories kev tsim lub tuam txhab. Lub Hoobkas yog vertically integrated. Lub Hoobkas muaj kev ua cov yas, hlau stamping, zinc tuag casting, SMT, DIP thiab Assembly center. Lub tuam txhab muaj lub zog nyiaj txiag muaj zog, pab pawg R&D kws tshaj lij, cov cuab yeej tsim khoom zoo tshaj plaws thiab kev tsim khoom lag luam, thiab mob siab rau tsim cov khoom zoo rau cov neeg siv khoom.
Dab tsi yog Txoj Kev Rov Qab Filter?
Nyob rau hauv RF kev sib txuas lus systems, ib tug rov qab txoj kev lim lim yog ib tug tivthaiv tsim los lim tawm tsis xav tau cov cim los yog suab nrov uas yuav cuam tshuam rau kev ua hauj lwm ntawm lub system. Nws pab xyuas kom meej tias cov teeb liab kis tau los ntawm ib lub cuab yeej lossis lub kaw lus mus rau lwm qhov chaw yog qhov tseeb ntawm kev cuam tshuam thiab suab nrov, tswj kev ncaj ncees ntawm kev sib txuas lus.
Txoj Kev Xa Rov Qab Ua Haujlwm Li Cas?
Rov qab txoj kev lim dej feem ntau yog siv ntau yam txuj ci, xws li passive LC (inductor-} capacitor) filtering, active filtering, lossis digital signal processing, los xaiv kom txo qis cov zaus lossis ntau zaus. Los ntawm thaiv cov cim tsis xav tau thaum tso cai rau cov teeb liab xav tau dhau mus, rov qab cov lim dej pab txhim kho cov teeb liab - rau - suab nrov piv thiab txhim kho tag nrho cov kev ua haujlwm ntawm lub cev.
Return Path Filters siv qhov twg?
Rov qab txoj kev lim dej pom cov ntawv thov hauv ntau yam kev sib txuas lus RF, suav nrog cable TV (CATV) tes hauj lwm, satellite kev sib txuas lus, broadband internet networks, thiab wireless kev sib txuas lus. Lawv feem ntau ua haujlwm nyob rau hauv transmitter-receiver setups uas tswj txoj kev rov qab huv si rau cov teeb liab yog qhov tseem ceeb rau kev sib txuas lus zoo.
FAQ
Q: Dab tsi yog cov txiaj ntsig ntawm kev siv Rov Qab Path Limers?
A: Los ntawm kev lim tawm qhov tsis xav tau cuam tshuam thiab suab nrov, rov qab cov lim dej pab txhim kho cov teeb liab zoo, txo cov teeb liab degradation, thiab txhim kho tag nrho cov kev ua tau zoo thiab kev ntseeg siab ntawm RF kev sib txuas lus. Lawv kuj tuaj yeem pab txo qis kev cuam tshuam ntawm electromagnetic cuam tshuam (EMI) thiab xyuas kom ua raws li cov qauv kev cai.
Q: Kuv yuav xaiv qhov Return Path Filter li cas rau kuv daim ntawv thov?
A: Xav txog yam xws li qhov ntau zaus ntawm kev ua haujlwm, qhov xav tau theem ntawm attenuation rau cov teeb liab tsis xav tau, kev tawm tswv yim / tso tawm impedance txuam cov cai, thiab ib puag ncig lossis kev tswj hwm kev xav. Kev sab laj nrog cov kws tshaj lij RF engineering lossis xa mus rau cov txheej txheem tshwj xeeb tuaj yeem pab xaiv qhov tsim nyog rov qab cov lim dej.
Q: Puas muaj ntau hom kev rov qab txoj kev lim dej?
A: Yog lawm, cov lim dej rov qab tuaj rau hauv ntau hom thiab teeb tsa, suav nrog cov lim dej tsis zoo, cov lim dej ua haujlwm, cov lim dej ntws tawm, cov lim dej coaxial, thiab cov lim dej sib xyaw ua ke. Kev xaiv hom lim yog nyob ntawm cov kev cai tshwj xeeb thiab kev txwv ntawm daim ntawv thov.
Q: Dab tsi yog qee qhov kev sib tw uas cuam tshuam nrog Rov Qab Path Lim?
A: Cov kev sib tw uas muaj xws li kev lag luam tawm - tawm ntawm kev ua haujlwm lim (attenuation, insertion poob) thiab lwm yam tsis zoo, xws li qhov loj me, nqi, thiab kev siv hluav taws xob. Kev tsim cov lim dej rov qab zoo kuj tseem yuav cuam tshuam txog cov teeb meem xws li impedance txuam, passband ripple, thiab nonlinear distortion.
Q: Puas muaj tej yam kev tu ncua rau Return Path Filters?
A: Rov qab txoj kev lim dej feem ntau tsis tas yuav muaj kev saib xyuas tsis tu ncua. Txawm li cas los xij, kev tshuaj xyuas ib ntus yuav tsim nyog los xyuas kom meej tias lub lim dej ua haujlwm kom raug thiab txhawm rau txheeb xyuas cov cim ntawm kev puas tsuaj lossis kev puas tsuaj uas yuav cuam tshuam rau nws txoj haujlwm. Nyob rau hauv tas li ntawd, yuav tsum tau hloov los yog kho.
