LCB-GSM/DCS/WCDMA-3 GSM DCS WCDMA Kaihanga
| Rangatira-mw | He kupu whakataki mo te roopu whakakotahi 6 |
Chengdu leader microwave Tech.,(leader-mw) GSM DCS WCDMA combiner, e mohiotia ana ano he multiplexer, he taputapu whai kiko me te tino whakamahia hei whakakotahi i nga tohu RF maha ki te tuku korekore.Ko tenei huinga huinga-3 e mahi ana i roto i te GSM 880-960MHz, DCS 1710-1880MHz me te WCDMA 1920-2170MHz awhe auau, ka waiho hei taputapu utu nui mo te arotau i te pai o te tuku i roto i nga momo whatunga whakawhitiwhiti.
Ka whakamahia e te whakakotahitanga he whirihoranga 3-i-1-waho ka hangaia kia pai te whakakotahi i nga tohu RF mai i nga momo tuku rereke me te tuku atu ki te taputapu tuku antenna.Ehara tenei i te mea ka ngawari noa te mahi tuku, engari ka awhina ano hoki ki te whakaiti i nga tohu tohu i waenga i nga tauranga rereke.
Ko te tikanga, he mahi nui a GSM DCS WCDMA Combiner ki te whakapai ake i te mahinga me te whai huatanga o nga whatunga korero.Ka taea e ia te whakakotahi me te whakahaere i nga tohu RF maha i te wa kotahi ki te whakarite kia pai ake te mahi whakawhiti me te pono.He tino whai hua tenei ki nga waahi he nui te nui o nga pukapuka waka, kei te hiahiatia ranei te whakauru ngawari o nga roopu auau rereke.
Ko te matua o te GSM DCS WCDMA whakakotahi he kaha ki te tukatuka i nga awhe auau motuhake o nga tohu GSM, DCS me WCDMA ki te whakatutuki i nga hiahia kanorau o nga punaha korero hou.Ma te whakarato i tetahi otinga matawhānui ki te whakakotahi i nga tohu i roto i enei roopu auau, ka whakaratohia e te whakakotahitanga te pai ake o te ngawari me te hototahi, ka waiho hei waahanga nui mo nga kaiwhakahaere whatunga me nga kaiwhakauru punaha.
