    Programmable-Gain Amp Boosts Cable Modems

    July 10, 2008
    ANADIGICS has introduced model ARA2017, a programmable-gain amplifier optimized for DOCSIS 3.0 cable-modem and E-MTA applications. It provides 33-dB gain from 5 to 85 MHz at its minimum gain setting, with an attenuation range of 0 to 58 dB that can be ...
    ANADIGICS has introduced model ARA2017, a programmable-gain amplifier optimized for DOCSIS 3.0 cable-modem and E-MTA applications. It provides 33-dB gain from 5 to 85 MHz at its minimum gain setting, with an attenuation range of 0 to 58 dB that can be adjusted in 2-dB increments by means of a three-wire serial interface. The amplifier consists of a low-noise-amplifier (LNA) input stage and linear output driver stage and is designed for use at +5 VDC. It is supplied in a 28-pin QFN, RoHS-compliant surface-mount package that measures 5 x 5 x 1 mm.
