Whakarāpopototanga Hua
Ko te SR812ST-R to matou hou-koeke teitei-rua-putanga CATV whatunga whatu kaiwhiwhi. Ko te whakahiato o mua ka tango i nga GaAs MMIC katoa, ko te pou-whakanui ka tango i te waahanga GaAs. Ko te hoahoa ara iahiko kua pai ake me o maatau 15 tau o te wheako hoahoa ngaio, kia eke nga taputapu ki nga tohu mahi pai. Ko te whakahaere microprocessor, te whakaaturanga mamati o nga tawhā, he tino ngawari te patuiro miihini. Koinei te taputapu matua ki te hanga i te whatunga CATV.
Nga Ahuatanga Mahinga
- Whakautu teitei PIN ngongo whakawhiti whakaahua hiko.
- Ko te hoahoa ara iahiko kua arotau, te hanga tukanga SMT, me te ara tohu pai kia pai ake te tuku tohu whakaahua hiko.
- Ko te maramara RF attenuation motuhake, me te pai o te RF attenuation me te raina taurite, te tino tika.
- Ko te taputapu whakakaha GaAs, te whakaputanga kairua mana, me te nui o te whiwhi me te iti o te korikori.
- Ko nga taputapu mana kotahi Chip Microcomputer (SCM) e mahi ana, e whakaatu ana te LCD i nga tawhā, te waatea me te mahi mohio, me te mahi pumau.
- He pai te mahinga AGC, ina he -9~+2dBm te awhe hiko whatu whakauru, ka noho tonu te taumata whakaputa, karekau e rerekee te CTB me te CSO.
- Ko te atanga whakawhitiwhiti korero raraunga kua rahuitia, ka taea te hono atu ki te akomanga Ⅱ te kaiwhakautu whakahaere whatunga, me te uru atu ki te punaha whakahaere whatunga.
- Ka taea e te tukunga hokinga te kowhiri i te aratau pakaru kia tino whakahekehia te haruru o te haruru me te whakaheke i te nama o mua.
He aha te korehaere ki to maatau wharangi whakapā, ka pai matou ki te korerorero ki a koe!
