PRODUCT 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.

S29 Package
28-Pin QFN
5 mm x 5 mm x 1 mm
The ARA2017 supports output power levels of +64
dBmV while minimizing harmonic, distortion, and
output noise levels. Its precision attenuator provides
up to 58 dB of attenuation in 2 dB increments. The
attenuator setting is programmed via a 3-wire serial
interface, as is the output stage current, a feature
which allows the device to be operated in reduced
power modes for extended backup battery life in
E-MTA applications. The ARA2017 is offered in a 28-
pin 5 mm x 5 mm x 1 mm QFN package.
