Sharaxaadda Badeecada
Soo Koobidda Badeecada
Qalabka ugu dambeeyay ee shirkaddayada ee afar-soo-saarka sare leh ee CATV network optical receiver SR814ST, qalabka hore u sii kordhiya wuxuu isticmaalaa GaAs MMIC oo buuxa, qalabka dambe ee sii kordhiya wuxuu isticmaalaa modules-ka GaAs. Iyada oo leh naqshad wareeg ah oo la hagaajiyay iyo 10 sano oo waayo-aragnimo naqshad xirfadeed ah, qalabku wuxuu gaaray tilmaameyaal waxqabad oo heer sare ah. Intaa waxaa dheer, xakamaynta microprocessor-ka iyo bandhigga halbeegga dijitaalka ah ayaa ka dhigaya khaladaadka injineernimada mid aad u fudud. Waa qalabka ugu muhiimsan ee lagama maarmaanka u ah dhismaha shabakadda CATV.
Astaamaha Waxqabadka
Qalabkayaga casriga ah ee qaataha indhaha ee shabakada CATV SR814ST wuxuu qaataa tuubada beddelka sawirka korontada ee PIN-ka oo jawaab celin sare leh, wuxuu hagaajiyaa naqshadeynta wareegga iyo wax soo saarka habka SMT, wuxuuna hirgeliyaa gudbinta siman oo hufan ee calaamadaha sawirka korontada.
Chips-yada RF ee gaarka ah waxay bixiyaan hoos u dhac toosan oo sax ah, halka aaladaha amplifier-ka GaAs ay bixiyaan faa'iido sare iyo qallooc hoose. Nidaamka waxaa maamula kombiyuutar yar oo hal-chip ah (SCM), oo leh cabbirro bandhig LCD ah, hawlgal fudud oo dareen leh, iyo waxqabad deggan.
Nidaamka AGC wuxuu hubiyaa in heerka wax soo saarku uu ahaado mid joogto ah oo ka sarreeya heerka awoodda indhaha ee -9 ilaa +2 dBm iyadoo faragelin yar ay ka imanayso CTB iyo CSO. Nidaamku wuxuu sidoo kale ku jiraa is-gaarsiin xog oo kaydsan, kaas oo lagu xidhi karo jawaab-bixiye maarayn shabakad nooca II ah oo lagu xidhi karo nidaamka maaraynta shabakadda. Dhammaan xuduudaha farsamada waxaa lagu cabbiraa iyadoo loo eegayo GY/T 194-2003, iyadoo la raacayo xaaladaha tijaabada ee caadiga ah.
