Sharaxaadda Badeecada
Soo Koobidda Badeecada
SR812ST-R waa qaataha indhaha ee ugu dambeeyay ee heerka sare ah ee CATV network laba-soo-saar ah. Qalabka hore u sii xoojiya wuxuu qaataa GaAs MMIC oo buuxa, qalabka dambe ee sii kordhiya wuxuu qaataa module-ka GaAs. Naqshadeynta wareegga ee la hagaajiyay oo ay weheliso 15-ka sano ee khibradda naqshadeynta xirfadeed, waxay ka dhigaysaa qalabku inuu gaaro tusmooyinka waxqabadka wanaagsan. Xakamaynta microprocessor-ka, soo bandhigida dhijitaalka ah ee xuduudaha, iyo hagaajinta injineernimada ayaa si gaar ah u fudud. Waa qalabka ugu weyn ee lagu dhiso shabakadda CATV.
Astaamaha Waxqabadka
- Tuubada beddelka sawir-qaadista ee PIN-ka oo jawaab celin sare leh.
- Naqshadeynta wareegga ee la hagaajiyay, soo saarista habka SMT, iyo wadada calaamadda ee la hagaajiyay waxay ka dhigaan gudbinta calaamadaha sawir-qaadista mid siman.
- Chip gaar ah oo RF ah oo yareynaya, oo leh RF wanaagsan iyo isku dheelitirnaan toosan, saxnaan sare.
- Qalabka amplifier-ka GaAs, wax soo saarka labajibbaaran ee awoodda leh, oo leh faa'iido sare iyo qallooc hoose.
- Qalabka xakamaynta ee Microcomputer-ka Keliya ee Chip-ka ah (SCM) oo shaqeynaya, LCD wuxuu soo bandhigayaa xuduudaha, ku habboonaanta iyo hawlgalka dareenka leh, iyo waxqabadka xasilloon.
- Waxqabadka AGC ee aadka u fiican, marka kala duwanaanshaha awoodda indhaha ee la gelinayo uu yahay －9～＋2dBm, heerka wax soo saarku isma beddelin, CTB iyo CSO-na asal ahaan isma beddelin.
- Is-dhexgalka isgaarsiinta xogta ee la keydiyay, wuxuu ku xidhi karaa jawaab-bixiyaha maaraynta shabakadda fasalka Ⅱ, wuxuuna geli karaa nidaamka maaraynta shabakadda.
- Qiiqa soo celinta wuxuu dooran karaa qaabka qarxa si uu si weyn u yareeyo isku-dhafka buuqa una yareeyo lambarka qaataha qaybta hore.
