Description

The ARA2017 is a highly linear, high output power, programmable gain amplifier optimized for DOCSIS 3.0 cable modem and E-MTA applications. Using a low noise input amplification stage and an ultra linear output driver amplifier, the device generates extremely low distortion products at the high output power levels required by DOCSIS 3.0 signals. Its balanced circuit design provides superior harmonic performance and an integrated digitally-controlled, multiple-stage precision step attenuator enables system solutions to meet DOCSIS power step accuracy requirements.
