Whakaahuatanga Hua
Whakarāpopototanga Hua
Ko te kaiwhiwhi whatu whatunga CATV putanga-whā hou a tā mātou kamupene, SR814ST, e whakamahi ana te whakakaha-mua i te GaAs MMIC katoa, ā, ko te whakakaha-muri e whakamahi ana i ngā kōwae GaAs. Nā te hoahoa ara iahiko kua arotauhia me te 10 tau o te wheako hoahoa ngaio, kua tutuki i te taputapu ngā tohu mahi tino pai. Hei tāpiri, mā te whakahaere tukatuka iti me te whakaaturanga tawhā mamati ka tino māmā te patuiro hangarau. Koinei te taputapu matua e hiahiatia ana mō te hanga whatunga CATV.
Ngā Āhuatanga Mahi
Ko tā mātou kaiwhiwhi whatu whatunga CATV matatau SR814ST e whakamahi ana i te ngongo tahuritanga whakaahua-hiko PIN urupare-teitei, e arotau ana i te hoahoa ara iahiko me te whakaputa tukanga SMT, ā, e whakatutuki ana i te tuku maeneene me te whai hua o ngā tohu whakaahua-hiko.
Mā ngā maramara whakaitiiti RF motuhake ka whakaratohia te whakaitiiti raina tika, ko ā mātou taputapu whakakaha GaAs ka whakaratohia he whakanui teitei me te whakapōturi iti. E whakahaerehia ana te pūnaha e tētahi rorohiko iti maramara-kotahi (SCM), me ngā tawhā whakaaturanga LCD, he mahi māmā me te mārama, me te mahi pumau.
Mā te pūnaha AGC ka noho pūmau te taumata putanga i runga i te awhe mana whatu mai i te -9 ki te +2 dBm me te iti o te pokanoa mai i te CTB me te CSO. Kei roto hoki i te pūnaha he atanga whakawhitiwhiti raraunga kua rāhuitia, ka taea te hono atu ki tētahi kaiwhakautu whakahaere whatunga momo II me te hono atu ki te pūnaha whakahaere whatunga. Ka inehia ngā tawhā hangarau katoa e ai ki te GY/T 194-2003, i raro i ngā tikanga whakamātautau paerewa.
