Whakaahuatanga Hua
Whakarāpopototanga Hua
Ko SR812ST-R tā mātou kaiwhiwhi whatu whatunga CATV putanga-rua kounga teitei hou. Ka whakamahia e te whakakaha-mua te MMIC GaAs-katoa, ka whakamahia e te whakakaha-muri te waeine GaAs. Nā te hoahoa ara iahiko kua arotauhia me ō mātou tau 15 o te wheako hoahoa ngaio, ka taea e ngā taputapu te whakatutuki i ngā taupū mahi pai. He tino māmā te whakahaere tukatuka iti, te whakaatu mamati o ngā tawhā, me te patuiro hangarau. Koinei te taputapu matua hei hanga i te whatunga CATV.
Ngā Āhuatanga Mahi
- Ngongo tahuritanga hiko PIN urupare teitei.
- Mā te hoahoa ara iahiko kua arotauhia, te whakaputa tukanga SMT, me te ara tohu kua arotauhia ka maeneene ake te tuku tohu hiko-whakaahua.
- Maramara whakaitiiti RF motuhake, he pai te whakaitiiti RF me te taurite raina, he tino tika.
- Pūrere whakakaha GaAs, putanga whakarua mana, me te whakanui teitei me te whakapōturi iti.
- Kei te mahi ngā taputapu whakahaere rorohiko iti maramara kotahi (SCM), e whakaatu ana te LCD i ngā tawhā, he ngāwari te whakahaere me te māmā hoki, ā, he pumau te mahi.
- He tino pai te mahi AGC, ina ko te awhe mana whatu tāuru he －9～＋2dBm, ka noho tonu te taumata putanga, ā, ko te CTB me te CSO kāore i te tino rerekē.
- Atanga whakawhitiwhiti raraunga kua rāhuitia, ka taea te hono atu ki te kaiwhakautu whakahaere whatunga akomanga 2, me te uru atu ki te pūnaha whakahaere whatunga.
- Ka taea e te tukunga whakahoki te tīpako i te aratau pakū hei whakaiti tere i te huihuinga haruru me te whakaiti i te maha o ngā kaiwhiwhi o mua.
