Whakaahuatanga Hua
Whakarāpopototanga Hua
Ko te hou o to taatau kamupene e wha nga putanga CATV he kaiwhiwhi whatu whatu SR814ST, ka whakamahia e te whakahiato i mua i te GaAs MMIC katoa, a ka whakamahia e te pou-whakanui i nga waahanga GaAs. Na te hoahoa ara iahiko papai me te 10 tau o te wheako hoahoa ngaio, kua tutuki i te taputapu nga tohu mahi pai. I tua atu, ko te whakahaere microprocessor me te whakaaturanga tawhā mamati he tino ngawari te mahi patuiro. Ko te taputapu matua e tika ana mo te hanga whatunga CATV.
Nga Ahuatanga Mahinga
Ko ta tatou kaikawe whatunga CATV matatau a SR814ST e tango ana i te ngongo whakawhiti whakaahua hiko PIN-whakautu nui, ka arotau i te hoahoa ara iahiko me te hanga tukanga SMT, me te mohio ki te tuku maeneene me te pai o nga tohu whakaahua hiko.
Ko nga maramara attenuation RF kua whakatapua e whakarato ana i te attenuation linear tika, i a maatau taputapu whakakaha GaAs e whakarato ana i nga taonga nui me te iti o te korikori. Ko te punaha e whakahaerehia ana e te miihini miihini kotahi (SCM), me nga tawhā whakaatu LCD, te mahi ngawari me te ngawari, me te mahi pumau.
Ko te punaha AGC ka whakarite kia noho tonu te taumata whakaputa i runga i te awhe hiko whatu o -9 ki te +2 dBm me te iti o te pokanoa mai i te CTB me te CSO. Kei roto hoki i te punaha he atanga whakawhitiwhiti korero raraunga kua rahuitia, ka taea te hono atu ki te momo II kaiwhakautu whakahaere whatunga me te hono atu ki te punaha whakahaere whatunga.Ka inehia nga tawhā hangarau katoa kia rite ki te GY / T 194-2003, i raro i nga tikanga whakamatautau paerewa.
