Electrical Characterization of the MAAMSS0031
16 dB Gain Application Circuit
Abstract
The MAAMSS0031 CATV amplifier is a GaAs MMIC
which exhibits low noise and high linearity. It is
ideally suited for set top boxes, home gateways, and
other broadband internet based appliances.
Functional Schematic
GND
This amplifier is a monolithic single stage design in
a 75 ohm input/output impedance environment. It is
designed to have a reduced number of external
matching components.

Introduction
The purpose of this application note is to present the
typical performance of the MAAMSS0031 amplifier
when it is operated at +8 Volts and tuned to provide
a small and large signal gain of 16 dB . It is intended
as an aid to engineers for the implementation of the
MAAMSS0031 in such a gain requirement circuit
and provides even lower noise figure than that
obtained using the nominal tuning.
