WR-1002-MH series are our universal CATV network optical receiver with network management transponder. The pre-amp adopts all-GaAs MMIC amplify and the post-amp adopts GaAs power double amplify module (This series has two models, M model RF attenuation and equilibrium adopt the continuously adjustable design, MF model with different fixed attenuation and equilibrium inserters for user option. Users can also choose more targeted high quality modules according to actual requirements). Optimized circuit design, coupled with our years professional RF design experience, the equipment achieve high performance index. It is an ideal model for CATV network.
