Functional Schematic
Description
M/A-COM’s MAAMSS0031 CATV amplifier is a
GaAs MMIC which exhibits low distortion in a
low-cost miniature surface mount plastic package.
The MAAMSS0031 employs a monolithic single
stage design featuring a convenient 75
Ω
input/
output impedance that minimizes the number of
external components required.
The MAAMSS0031 provides low noise and high
linearity. It is ideally suited for set top boxes, home
gateways, and other broadband internet based
appliances.
The MAAMSS0031 is fabricated using M/A-COM’s
PHEMT process to realize low noise and low
distortion. The process features full passivation for
robust performance and reliability.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
