ARF120D RF Amplifier

ARF120D Series 1.2 GHz 1 or 2 output GaAs amplifier is part of ACT Advanced Fiber Deep HFC solution, which has been designed to deliver interactive CATV, high capacity DOCSIS and other advanced services. The cost effective last mile amplifier platform helps operators expand bandwidth of their existing HFC network while minimizing capital investment. The ARF120D compact housing has compact housing with embedded RF module and is suitable for MDU, FTTB or FTTC applications with output up to 108 dBµV.

    Supports 1.2 GHz bandwidth

    Up to 204 MHz with return bandwidth

    Minimum needed of installing and maintaining accessories such as pads and EQs

    Local monitoring, control and set up via APP or 3-bit digital tube display and adjust keypad

    On-site changing frequency split  

    Reverse path gain adjust switching and passive

    Compact design

    GaAs technology

    Improved ESD and surge protection

    Low noise figure

    One or two output can be determined by the splitter position
