PRODUCT DESCRIPTION
The ARA05050 is a GaAs IC designed to provide the
reverse path amplification and output level control
functions in a CATV Set-Top Box or Cable Modem. It
incorporates a digitally controlled precision step
attenuator that is preceded by an ultra low noise
amplifier stage, and followed by an ultra-linear output
driver amplifier. This device is capable of meeting
the MCNS/DOCSIS requirements for harmonic

performance at a +58dBmV output level while
requiring only a single polarity +5V supply. Both the
input and the output are single-ended and matched
to 75 Ohms. The precision attenuator provides up to
30 dB of attenuation in 2 dB increments. The
ARA05050 is offered in a 28-pin SSOP package that
features a heat slug on the bottom of the package,
and is available in a RoHS-compliant option.
