Whakaahuatanga Hua
1. Whakarāpopototanga o te Hua
Ko SR812S tā mātou kaiwhiwhi whatu whatunga CATV whānui me te transponder whakahaere whatunga. Ka whakamahia e te pre-amp te whakakaha MMIC GaAs katoa, ā, ka whakamahia e te post-amp te waeine whakakaha rua mana GaAs. Nā te hoahoa ara iahiko kua arotauhia, me ō mātou tau wheako hoahoa RF ngaio, ka tutuki i te taputapu te taupū mahi teitei. He tauira tino pai mō te whatunga CATV.
2. Āhuatanga
- Ngongo tahuritanga hiko PIN urupare teitei, hoahoa whānui 1G.
- Ka taea te whakarite tonu i te whakaiti me te whakataurite i te momo poroporomomo whakauru rānei. (Whiringa)
- Putanga whakarea mana, whakanui teitei me te whakapōturi iti.
- Mana whakahaere AGC whatu, ina ko te awhe mana whatu tāuru he －7～＋2dBm, kāore te taumata putanga e rerekē.
- He taputapu whakawhiti whatunga kōwhiringa, tautoko i te pūnaha whakahaere whatunga NMS.
