Incazelo Yomkhiqizo
Isifinyezo somkhiqizo
Inethiwekhi yakamuva ye-CATV ene-optical receiver yenkampani yethu ephuma ezine yokugcina ephezulu engu-SR814ST, i-pre-amplifier isebenzisa ama-GaAs MMIC agcwele, kanti i-post-amplifier isebenzisa amamojula we-GaAs. Ngomklamo olungiselelwe wesifunda kanye neminyaka eyi-10 yesipiliyoni sokuklama kochwepheshe, idivayisi izuze izinkomba zokusebenza ezinhle kakhulu. Ngaphezu kwalokho, isilawuli se-microprocessor nesibonisi sepharamitha yedijithali kwenza ukulungisa iphutha lobunjiniyela kube lula kakhulu. Yimishini esemqoka edingekayo ekwakheni inethiwekhi ye-CATV.
Izimpawu Zokusebenza
Isamukeli sethu esithuthukisiwe senethiwekhi ye-CATV ye-optical receiver SR814ST yamukela ishubhu yokuguqulela ye-PIN photoelectric enempendulo ephezulu, ithuthukisa ukwakheka kwesekethe kanye nokukhiqizwa kwenqubo ye-SMT, futhi ibona ukudluliswa okushelelayo nokuphumelelayo kwamasignali ombane wezithombe.
Ama-chips e-RF attenuation anikezela ukuncishiswa komugqa okunembe, kuyilapho amadivayisi wethu we-GaAs amplifier ahlinzeka ngenzuzo ephezulu kanye nokuhlanekezela okuphansi. Uhlelo lulawulwa yi-single-chip microcomputer (SCM), enemingcele yokubonisa i-LCD, ukusebenza okulula nokunembile, nokusebenza okuzinzile.
Uhlelo lwe-AGC luqinisekisa ukuthi izinga lokukhiphayo lihlala linjalo phezu kwebanga lamandla okubonayo elingu--9 kuya ku-+2 dBm ngokuphazanyiswa okuncane okuvela ku-CTB ne-CSO. Uhlelo luphinde luhlanganise isixhumi esibonakalayo sokuxhumana kwedatha egodliwe, esingaxhunywa kusiphenduli sokuphathwa kwenethiwekhi yohlobo lwe-II futhi sixhunywe ohlelweni lokuphatha inethiwekhi.Yonke imingcele yobuchwepheshe ikalwa ngokwe-GY/T 194-2003, ngaphansi kwezimo zokuhlola ezijwayelekile.
Awuqinisekile okwamanje?
Kungani kungenjalovakashela ikhasi lethu lokuxhumana, singathanda ukuxoxa nawe!
