CATV Reverse Amplifier w/ Step Attenuator
Advanced product information
Rev. 6
DESCRIPTION
The ARA05050 is a GaAs IC designed to perform 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. It is capable of meeting the MCNS/DOCSIS
harmonic distortion specifications while only requiring a
single polarity +5V supply. This part is a single ended
design that does not require an output balun to achieve
-55 dBc 2nd harmonic performance at +58 dBmV output
FEATURES
Integrated monolithic GaAs amplifier and step
attenuator.
Compatible with all digital and analog modulation types.
Frequency range: 5 - 100 MHz.
Gain: 0 - 30 dB, variable in 2 dB steps.
5 Volt operation.
Low noise figure.
Low distortion.
Amplifier shutdown capability.
Low cost.
High reliability.
Low signal to noise ratio at all gain levels.

levels. Both the input and output are
matched to 75 ohms. The precision
attenuator provides up to 30 dB of
attenuation in 2 dB increments. The
ARA05050 is supplied in a 28-pin SSOP
package featuring a thermal heat slug on
the bottom of the package. Soldering this
heat slug to the ground plane of the PC
board ensures the lowest possible thermal
resistance for the device resulting in a
long MTF.
