IsiShwankathelo seMveliso
Inkampani yethu yamva nje yeziphumo ezine ze-CATV yenethiwekhi ye-optical receiver SR814ST, i-amplifier yangaphambili isebenzisa i-GaAs MMIC epheleleyo, kunye ne-post-amplifier isebenzisa iimodyuli ze-GaAs. Ngoyilo lwesekethe oluphuculweyo kunye neminyaka eyi-10 yamava oyilo lobuchwephesha, isixhobo sifezekise izikhombisi zokusebenza ezigqwesileyo. Ukongeza, ulawulo lwe-microprocessor kunye nomboniso weparamitha yedijithali yenza ukulungisa iimpazamo zobunjineli kube lula kakhulu. Sesona sixhobo siphambili esiyimfuneko ekwakheni inethiwekhi yeCATV.
Iimpawu zoMsebenzi
Inethiwekhi yethu ye-CATV ephucukileyo ye-optical receiver SR814ST isebenzisa ityhubhu yokuguqula i-PIN photoelectric ephezulu, ikhulisa uyilo lwesekethe kunye nokuveliswa kwenkqubo ye-SMT, kwaye iqonda ukuhanjiswa okungenamagingxigingxi kunye nokusebenza kakuhle kweempawu zombane.
Iichips ezinikezelweyo zeRF zokuthomalalisa zibonelela ngokuthe ngqo kumgca wokuthomalalisa, ngelixa izixhobo zethu zeamplifier ze-GaAs zibonelela ngenzuzo ephezulu kunye nokugqwetheka okuphantsi. Inkqubo ilawulwa yi-single-chip microcomputer (SCM), kunye neeparitha zokubonisa i-LCD, ukusebenza okulula kunye nokubonakalayo, kunye nokusebenza okuzinzile.
Inkqubo ye-AGC iqinisekisa ukuba inqanaba lemveliso lihlala lingaguquguquki kuluhlu lwamandla okukhanya ukusuka ku -9 ukuya +2 dBm kunye nokuphazamiseka okuncinci okuvela kwi-CTB kunye neCSO. Inkqubo iphinda iquka i-interface yonxibelelwano lwedatha egciniweyo, enokuthi idibaniswe nohlobo lwe-II umphenduli wolawulo lwenethiwekhi kwaye iqhagamshelwe kwinkqubo yokulawula inethiwekhi.Zonke iiparitha zobugcisa zilinganiswa ngokwe-GY / T 194-2003, phantsi kweemeko zovavanyo oluqhelekileyo.
Ngoba kuthenindwendwela iphepha lethu loqhagamshelwano, singathanda ukuncokola nawe!
