SR812ST-R shine sabon mai karɓar gani na cibiyar sadarwar CATV mai inganci mai inganci biyu. Mai ƙara girman yana ɗaukar cikakken GaAs MMIC, mai ƙara girman yana ɗaukar tsarin GaAs. Tsarin da'ira mai kyau tare da shekaru 15 na ƙwarewar ƙira ta ƙwararru, yana sa kayan aikin su cimma kyakkyawan ma'aunin aiki. Kula da microprocessor, nunin dijital na sigogi, da gyara injiniyan suna da sauƙi musamman. Ita ce babban kayan aikin gina cibiyar sadarwar CATV.
Halayen Aiki
- Bututun canza wutar lantarki mai ƙarfi na PIN mai amsawa.
- Tsarin da'ira da aka inganta, samar da tsarin SMT, da kuma ingantaccen hanyar sigina suna sa watsa siginar photoelectric ya fi santsi.
- Ƙwararren guntu na rage RF, tare da kyakkyawan rage RF da daidaitaccen layi, babban daidaito.
- Na'urar ƙara ƙarfin GaAs, fitowar wutar lantarki mai ninka biyu, tare da babban riba da ƙarancin karkacewa.
- Kayan aikin sarrafa Microcomputer guda ɗaya (SCM) suna aiki, LCD yana nuna sigogi, dacewa da aiki mai fahimta, da kuma aiki mai dorewa.
- Kyakkyawan aikin AGC, lokacin da ƙarfin wutar lantarki na gani ya kai ⼍9～＋2dBm, matakin fitarwa yana ci gaba da canzawa, kuma CTB da CSO ba su canzawa ba.
- Tsarin sadarwa na bayanai da aka adana, zai iya haɗawa da mai amsa cibiyar sadarwa ta aji Ⅱ, da kuma samun damar tsarin gudanar da cibiyar sadarwa.
- Fitar da hayaki daga dawowa na iya zaɓar yanayin fashewa don rage yawan hayaniyar da kuma rage adadin mai karɓar gaba.
