Chidule cha Zamalonda
Cholandirira chaposachedwa kwambiri cha CATV network optical receiver SR814ST cha kampani yathu, pre-amplifier imagwiritsa ntchito GaAs MMIC yonse, ndipo post-amplifier imagwiritsa ntchito ma module a GaAs. Ndi kapangidwe kabwino ka circuit komanso zaka 10 zaukadaulo wopanga, chipangizochi chapeza zizindikiro zabwino kwambiri zogwirira ntchito. Kuphatikiza apo, kuwongolera ma microprocessor ndi chiwonetsero cha digito zimapangitsa kuti kukonza zolakwika paukadaulo kukhale kosavuta kwambiri. Ndi chipangizo chofunikira kwambiri popanga netiweki ya CATV.
Makhalidwe Ogwira Ntchito
Cholandirira chathu chapamwamba cha CATV network optical SR814ST chimagwiritsa ntchito chubu chosinthira ma photoelectric cha PIN chomwe chimayankha bwino, chimakonza kapangidwe ka ma circuit ndi kupanga njira za SMT, komanso chimatumiza ma signal a photoelectric mosavuta komanso moyenera.
Ma chips odzipereka a RF attenuation amapereka kutsika kolondola kwa mzere, pomwe zida zathu za GaAs amplifier zimapereka kukwera kwakukulu komanso kusokonekera kochepa. Dongosololi limayang'aniridwa ndi kompyuta yaying'ono ya single-chip (SCM), yokhala ndi magawo owonetsera a LCD, ntchito yosavuta komanso yodziwikiratu, komanso magwiridwe antchito okhazikika.
Dongosolo la AGC limaonetsetsa kuti mulingo wotuluka umakhalabe wofanana pa mphamvu ya kuwala kuyambira -9 mpaka +2 dBm popanda kusokonezedwa kwambiri ndi CTB ndi CSO. Dongosololi limaphatikizaponso mawonekedwe olumikizirana deta osungidwa, omwe amatha kulumikizidwa ku responder ya mtundu wa II network management ndikulumikizidwa ku network management system. Ma parameter onse aukadaulo amayesedwa malinga ndi GY/T 194-2003, pansi pa mikhalidwe yoyesera yokhazikika.
