Sharaxaada Alaabta

Soo koobida alaabta

SR812ST-R waa heerkeenii ugu dambeeyay ee heerka sare ee laba-soo-saarka CATV soo-dhoweeyaha indhaha. Cod-weyneeye ka hor wuxuu qaataa-GaAs MMIC oo buuxa, cod-sameeyaha dambe wuxuu qaataa moduleka GaAs. Naqshad wareeg ah oo la hagaajiyay oo ay weheliso 15 sano ee waayo-aragnimada naqshadaynta xirfadeed, waxay ka dhigtaa qalabku inuu gaaro tusmooyinka waxqabadka wanaagsan. Xakamaynta Microprocessor, soo bandhigida dhijitaalka ah ee cabirrada, khaladka injineernimada ayaa si gaar ah u fudud. Waa qalabka ugu muhiimsan ee lagu dhisayo shabakada CATV.

 

Tilmaamaha Waxqabadka

- Jawaab sare tuubada beddelka sawir-qaadaha PIN.
- Naqshad wareeg ah oo la wanaajiyey, wax soo saarka habka SMT, iyo dariiqa calaamadaha la hagaajiyay ayaa ka dhigaya gudbinta signalka sawir-qaadista mid siman.
- Chip attenuation RF gaar ah, oo leh feejignaan RF wanaagsan iyo toosan siman, saxsanaan sare.
- Qalabka cod-weyneeye ee GaAs, wax soo saarka labajibbaaran ee awoodda, oo leh faa'iido sare iyo qallooc hoose.
- Hal Chip Microcomputer (SCM) qalabka kontoroolka ee shaqeynaya, LCD waxay soo bandhigtaa cabbirada, ku habboonaanta iyo hawlgalka dareenka leh, iyo waxqabadka xasilloon.
- Waxqabadka AGC heer sare ah, marka cabbirka awoodda indhaha ee wax gelinta uu yahay -9 ~+2dBm, heerka wax soo saarku isma beddelo, iyo CTB iyo CSO asal ahaan isma beddelaan.
- Interface isgaadhsiinta xogta kaydsan, waxay ku xidhmi kartaa fasalka Ⅱ maamulka shabakada jawaabaha, oo geli kara nidaamka maaraynta shabakada.
Soo-celinta soo-celinta waxay dooran kartaa qaabka dillaaca si uu si xooggan u yareeyo isku-dhafka dhawaaqa oo loo yareeyo lambarka hore ee qaataha.
