Soo koobida alaabta
Shirkaddeena ugu dambaysay afarta-dhamaadka sare ee soosaarka shabakada CATV soodhaweeyaha indhaha SR814ST, cod-sameeyaha hore wuxuu isticmaalaa GaAs MMIC buuxa, iyo cod-weyneeye ka dambeeya wuxuu isticmaalaa modules GaAs.Naqshadeynta wareegga la hagaajiyay iyo 10 sano oo waayo-aragnimo naqshadeyn xirfadeed ah, qalabku wuxuu ku guuleystay tilmaamayaasha waxqabadka wanaagsan.Intaa waxaa dheer, kontoroolka microprocessor-ka iyo soo bandhigida cabbirka dhijitaalka ah ayaa ka dhigaya cilladaha injineernimada mid aad u fudud.Waa qalabka ugu muhiimsan ee lagama maarmaanka u ah dhismaha shabakada CATV.
Tilmaamaha Waxqabadka
Shabakadeena horumarsan ee CATV Iibiyaha indhaha SR814ST waxay qabataa jawaabta sare ee tuubada beddelka sawir-qaadista PIN, waxay wanaajisaa naqshadaynta wareegga iyo wax soo saarka habka SMT, waxayna garwaaqsataa gudbinta hufan oo hufan ee calaamadaha korantada.
Chips attenuation RF ee u go'ay ayaa bixiya attenuation toosan, halka aaladaha gaAs-ga cod-weyneyayaashu ay bixiyaan faa'iido sare iyo qallooc hoose.Nidaamka waxaa gacanta ku haya microcomputer hal-chip ah (SCM), oo leh cabbiraadaha bandhiga LCD, hawl fudud oo dareen leh, iyo waxqabad deggan.
Nidaamka AGC wuxuu hubinayaa in heerka wax-soo-saarku uu si joogto ah uga sarreeyo baaxadda awoodda indhaha ee -9 illaa +2 dBm iyada oo faragelin yar ay ka timaad CTB iyo CSO.Nidaamku waxa kale oo ku jira isgaadhsiinta isgaadhsiinta xogta ee kaydsan, kaas oo lagu xidhi karo nooca II jawaab-celinta maareynta shabakada oo lagu xiro nidaamka maareynta shabakada.Dhammaan xuduudaha farsamada waxaa lagu qiyaasaa sida waafaqsan GY / T 194-2003, iyada oo la raacayo shuruudaha imtixaanka caadiga ah.
