1. Takaitaccen Bayani
SR812S sune mai karɓar gani na cibiyar sadarwa na CATV na duniya tare da transponder sarrafa cibiyar sadarwa. The pre-amp yana ɗaukar duk-GaAs MMIC haɓakawa kuma post-amp ya ɗauki GaAs ikon ƙara haɓaka sau biyu. Ingantacciyar ƙirar da'ira, haɗe tare da ƙwararrun ƙirar ƙirar RF na shekarunmu, kayan aikin sun sami babban ma'aunin aiki. Yana da kyakkyawan samfuri don cibiyar sadarwar CATV.
2. Siffar
- Babban amsa PIN photoelectric bututu, ƙirar bandwidth 1G.
- Attenuation da daidaitawa na iya kasancewa nau'in ƙwanƙwasa daidaitacceko saka nau'in.(Na zaɓi)
- Power doubler fitarwa, babban riba da ƙananan murdiya.
- Ikon AGC na gani, lokacin shigar da kewayon wutar lantarki -7 ~ 2dBm, matakin fitarwa a zahiri bai canza ba.
- Transponder cibiyar sadarwa na zaɓi, goyan bayan tsarin sarrafa cibiyar sadarwar NMS.
