Description
M/A-COM's MAAMSS0031 CATV amplifier is a
GaAs MMIC which exhibits low distortion in a
low-cost miniature SOT-89 surface mount
plastic package. The MAAMSS0031 employs
a monolithic single stage design featuring a
convenient 75 Ohm 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.
