1. Chidule cha Zamalonda

SR812S ndi cholandirira chathu cha CATV chapaintaneti chodziwika bwino chokhala ndi transponder yoyang'anira maukonde. Pre-amp imagwiritsa ntchito amplifier ya GaAs MMIC yonse ndipo post-amp imagwiritsa ntchito module ya GaAs power double amplifier. Kapangidwe kabwino ka dera, pamodzi ndi luso lathu la zaka zambiri pakupanga ma RF, zidazi zimakhala ndi chiwongola dzanja chapamwamba. Ndi chitsanzo chabwino kwambiri cha netiweki ya CATV.

2. Mbali

- Chubu chosinthira mphamvu ya PIN yoyankha bwino, kapangidwe ka bandwidth ya 1G.
- Kuchepetsa ndi kulinganiza zinthu kungakhale kosinthika nthawi zonsekapena ikani mtundu. (Mwasankha)
- Mphamvu yowirikiza kawiri, phindu lalikulu komanso kusokonekera kochepa.
- Kuwongolera kwa AGC Yowoneka bwino, pamene mphamvu yolowera ya kuwala ndi －7～＋2dBm, mulingo wotulutsa sunasinthe kwenikweni.
- Transponder yosankha ya netiweki, yothandizira njira yoyendetsera ma netiweki ya NMS.
