Low Cost SOIC 8 Plastic Package
D e s c r i p t i o n
M/A-COM's AM50-0002 is a high perf o rmance GaAs
MMIC low noise amplifier in a low cost SOIC 8-lead surface mount plastic package. The AM50-0002 employs a
monolithic 3-stage self-bias design and a simple extern a l
matching network to obtain minimum noise figure. It can
be biased using 3- or 5-volt supplies.
The AM50-0002 is ideally suited for use where low noise
f i g u re, high gain, high dynamic range and low power
consumption are re q u i red. Typical applications include
receiver front ends in the Global Positioning System
(GPS) market, as well as standard gain blocks, buff e r
amps, driver amps and IF amps in both fixed and
portable systems.
M/A-COM's AM50-0002 is fabricated using a mature 0.5m i c ron gate length GaAs process. The process feature s
full passivation for increased perf o rmance re l i a b i l i t y .
