Anadigics launches first programmable gain amplifier optimized for DOCSIS 3.0 cable modems and E-MTA

Anadigics Inc of Warren, NJ, USA has launched what it claims is the first programmable gain amplifier optimized for DOCSIS 3.0 cable modem and E-MTA applications. The ARA2017 supports high linear power levels, enabling channel bonding and thus higher data rates in the cable system upstream (return) path.

Operating in the 5-85MHz frequency range, the device supports DOCSIS 3.0-specified signal levels of +64dBmV while minimizing harmonic distortion and output noise levels. At minimum attenuation, the ARA2017 has 33dB of RF gain. An integrated, digitally controlled, multi-stage precision step attenuator provides up to 58dB of attenuation in 2dB increments. Requiring a single 5V supply, the device is offered in a 28-pin 5mm x 5mm x 1mm QFN package.

The ARA2017 is integral to the performance of DOCSIS 3.0 terminal products, and is used by multiple vendors in cable modems that were certified for DOCSIS 3.0 usage, based on recent testing at CableLabs.

“The ARA2017 is an example of our firm commitment to developing products ahead of the technology curve, and its performance allows cable system operators to provide higher two-way data rates and enhanced service offerings,” says Ron Michels, senior VP and general manager of Anadigics’ Broadband Business.

The device is priced at $3.60 in quantities of 5000 units.
