Description
M/A-COM's AM50-0002 is a high performance GaAs
MMIC low noise amplifier in a SOIC 8-lead surface
mount plastic package. The AM50-0002 employs a
monolithic 3-stage self-bias design and a simple
external matching network to obtain minimum noise
figure.
The AM50-0002 is ideally suited for use where low
noise figure, high gain, high dynamic range and low
power consumption are required. Typical
applications include receiver front ends in the Global
Positioning System (GPS) market, as well as
standard gain blocks, buffer amps, driver amps, and
IF amps in both fixed and portable systems.
M/A-COM'S AM50-0002 is fabricated using a mature
0.5-micron gate length GaAs process. The process
features full passivation for increased performance
reliability.
