LCB-GSM/DCS/WCDMA-3 GSM DCS WCDMA Combiner
| Tus thawj coj-mw | Taw qhia rau 6 band combiner |
Chengdu tus thawj coj microwave Tech., (leader-mw) GSM DCS WCDMA combiner, tseem hu ua multiplexer, yog ib qho khoom siv ntau yam thiab tseem ceeb uas siv los sib txuas ntau lub teeb liab RF rau hauv ib qho kev sib kis tsis muaj kev sib txuas. Lub combiner 3-band no ua haujlwm hauv GSM 880-960MHz, DCS 1710-1880MHz thiab WCDMA 1920-2170MHz zaus ntau yam, ua rau nws yog ib qho cuab yeej muaj txiaj ntsig zoo rau kev ua kom zoo dua ntawm kev sib kis hauv ntau lub network sib txuas lus.
Lub combiner siv 3-hauv-1-tawm configuration thiab yog tsim los ua kom zoo RF teeb liab los ntawm ntau lub transmitters thiab xa lawv mus rau lub antenna transmitting device. Qhov no tsis yog tsuas yog ua kom yooj yim rau cov txheej txheem kis, tab sis kuj pab txo qhov cuam tshuam ntawm cov teeb liab ntawm ntau lub ports.
Qhov tseeb, GSM DCS WCDMA Combiner ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm cov tes hauj lwm sib txuas lus. Nws tuaj yeem sib koom ua ke thiab tswj ntau lub teeb liab RF tib lub sijhawm kom ntseeg tau tias muaj kev sib kis zoo dua thiab txhim khu kev qha dua. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv thaj chaw uas muaj cov tsheb khiav ntau lossis qhov twg xav tau kev sib koom ua ke ntawm cov zaus sib txawv.
Lub hauv paus ntawm GSM DCS WCDMA combiner muaj peev xwm ua cov zaus tshwj xeeb ntawm GSM, DCS thiab WCDMA cov teeb liab kom tau raws li ntau yam kev xav tau ntawm cov kab ke sib txuas lus niaj hnub. Los ntawm kev muab cov kev daws teeb meem dav dav los sib txuas cov teeb liab hauv cov zaus no, lub combiner muab kev ywj pheej thiab kev sib raug zoo dua, ua rau nws yog ib qho tseem ceeb rau cov neeg teb xov tooj network thiab cov neeg koom ua ke.
