ANADIGICS' (www.anadigics.com) latest upstream path RF amplifier, the ARA2021, is intended for use in DOCSIS-compliant cable modems, cable set-top boxes, residential gateways and EMTAs. Designed to support a new high power operation mode in the recently amended DOCSIS 3.0 spec, the ARA2021 is designed to provide a faster upstream to subscribers located farther from the headend, and also to reduce power consumption by up to 97% in standby mode.

It supports linear output power levels up to +67 dBmV (single channel), integrates a step attenuator with up to 49 dB of attenuation in 1 dB increments, features 35 dB of RF voltage gain (at minimum attenuation), is offered in a 20-pin, 4 mm x 4 mm x 1 mm MLPQ (QFN) package, operates from 5-85 MHz, and includes a low-power Transmit Disable (standby) mode that consumes only 35 mW.
