LCB-GSM/DCS/WCDMA-3 GSM Isku-darka DCS WCDMA

Chengdu leader microwave Tech.,(leader-mw) Isku-darka GSM DCS WCDMA, oo sidoo kale loo yaqaan multiplexer, waa qalab badan oo lagama maarmaan ah oo loo isticmaalo in lagu daro calaamadaha RF badan hal gudbin oo aan kala go 'lahayn. Isku-darka 3-band wuxuu ka shaqeeyaa heerarka soo noqnoqda ee GSM 880-960MHz, DCS 1710-1880MHz iyo WCDMA 1920-2170MHz, taasoo ka dhigaysa qalab qiimo leh oo lagu hagaajinayo hufnaanta gudbinta shabakadaha isgaarsiinta ee kala duwan.

Isku-darka wuxuu adeegsadaa qaabeyn 3-in-1-out ah waxaana loogu talagalay inuu si hufan isugu daro calaamadaha RF ee ka imanaya gudbiyeyaasha kala duwan oo uu u geeyo qalabka gudbinta anteenada. Tani ma aha oo kaliya inay fududeyso habka gudbinta, laakiin sidoo kale waxay gacan ka geysaneysaa yareynta faragelinta calaamadaha ee ka dhex dhici kara dekedaha kala duwan.

Xaqiiqdii, GSM DCS WCDMA Combiner wuxuu door muhiim ah ka ciyaaraa hagaajinta waxqabadka guud iyo waxtarka shabakadaha isgaarsiinta. Waxay isku dari kartaa oo maamuli kartaa calaamado badan oo RF ah isku mar si loo hubiyo hab gudbin oo siman oo la isku halleyn karo. Tani waxay si gaar ah faa'iido ugu leedahay meelaha leh mugga taraafikada sare ama meesha loo baahan yahay isku-darka aan kala go 'lahayn ee xargaha soo noqnoqda ee kala duwan.

Xudunta isku-darka GSM DCS WCDMA wuxuu awood u leeyahay inuu farsameeyo noocyada soo noqnoqda ee gaarka ah ee calaamadaha GSM, DCS iyo WCDMA si loo daboolo baahiyaha kala duwan ee nidaamyada isgaarsiinta casriga ah. Iyadoo la bixinayo xal dhammaystiran oo lagu isku daro calaamadaha ku jira silsiladaha soo noqnoqda, isku-darka wuxuu bixiyaa dabacsanaan iyo is-waafajin la xoojiyay, taasoo ka dhigaysa qayb muhiim ah oo loogu talagalay hawl wadeennada shabakadda iyo isku-duwayaasha nidaamka.
