LCB-GSM/DCS/WCDMA-3 GSM DCS WCDMA Combiner
| Leader-mw | Taw qhia rau 6 band combiner |
Chengdu tus thawj coj microwave Tech., (tus thawj coj-mw) GSM DCS WCDMA combiner, los yog ib tug multiplexer, yog ib tug ntau yam thiab tseem ceeb ntaus ntawv siv los ua ke ntau yam RF signals rau hauv ib tug seamless kis tau tus mob. Qhov no 3-band combiner ua haujlwm nyob rau hauv GSM 880-960MHz, DCS 1710-1880MHz thiab WCDMA 1920-2170MHz zaus ntau yam, ua rau nws yog ib qho cuab yeej tseem ceeb rau optimizing kev sib kis tau zoo hauv ntau yam kev sib txuas lus.
Lub tshuab ua ke siv 3-hauv-1-tawm kev teeb tsa thiab tsim kom muaj txiaj ntsig zoo sib txuas RF cov cim los ntawm cov khoom sib txawv thiab xa mus rau cov kav hlau txais xov xa xov. Qhov no tsis tsuas yog ua kom yooj yim rau txoj kev sib kis, tab sis kuj pab txo cov teeb liab cuam tshuam ntawm cov chaw nres nkoj sib txawv.
Qhov tseeb, GSM DCS WCDMA Combiner ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov kev ua tau zoo thiab kev ua tau zoo ntawm kev sib txuas lus. Nws tuaj yeem ua ke thiab tswj ntau lub teeb liab RF ib txhij los xyuas kom meej cov txheej txheem sib kis tau zoo dua thiab txhim khu kev qha. Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv cov cheeb tsam uas muaj cov tsheb thauj mus los loj lossis qhov chaw sib txuas tsis sib haum ntawm cov kab sib txawv yuav tsum tau ua.
Lub hauv paus tseem ceeb ntawm GSM DCS WCDMA combiner muaj peev xwm ua tiav qhov ntau zaus ntawm GSM, DCS thiab WCDMA cov cim kom tau raws li qhov xav tau ntawm ntau hom kev sib txuas lus niaj hnub. Los ntawm kev muab cov kev daws teeb meem los ua ke cov teeb liab hauv cov kab hluav taws xob ntau, cov khoom sib txuas muab kev txhim kho yooj yim thiab kev sib raug zoo, ua rau nws yog ib qho tseem ceeb rau cov tswv lag luam network thiab cov kev sib koom ua ke.
