SR812ST-R shine sabon babban sa biyu na fitarwa CATV mai karɓar gani na cibiyar sadarwa. The pre-amplifier yana ɗaukar cikakken-GaAs MMIC, bayan-amplifier yana ɗaukar tsarin GaAs. Ingantattun ƙirar da'ira tare da shekaru 15 na ƙwarewar ƙira na ƙwararru, sa kayan aikin su sami maƙasudin ayyuka masu kyau. Ikon Microprocessor, nuni na dijital na sigogi, gyara aikin injiniya yana da sauƙi musamman. Yana da babban kayan aiki don gina cibiyar sadarwar CATV.
Halayen Aiki
- High amsa PIN photoelectric tuba tube.
- Ingantaccen ƙirar kewayawa, samar da tsarin SMT, da ingantacciyar hanyar sigina ta sa siginar siginar hoto ya fi santsi.
- guntu na musamman na RF attenuation, tare da kyakkyawan RF attenuation da madaidaiciyar madaidaiciya, babban daidaito.
- GaAs amplifier na'urar, fitarwa mai ƙarfi biyu, tare da babban riba da ƙarancin murdiya.
- Single Chip Microcomputer (SCM) kayan sarrafa kayan aiki, LCD yana nuna sigogi, dacewa da aiki mai fahimta, da kwanciyar hankali.
- Kyakkyawan aikin AGC, lokacin shigar da kewayon ikon gani ya kasance -9 ~ 2dBm, matakin fitarwa yana ci gaba da canzawa, kuma CTB da CSO ba su canzawa.
- Keɓaɓɓen hanyar sadarwar sadarwar bayanai, na iya haɗawa tare da mai amsawa mai sarrafa cibiyar sadarwa na aji Ⅱ, da samun damar tsarin gudanarwar cibiyar sadarwa.
- Komawa na iya zaɓar yanayin fashewa don rage yawan hayaniyar da rage lambar mai karɓar gaba.
