Description
M/A-COM’s MAAM12021 is a high performance
GaAs MMIC low noise amplifier in a low cost SOIC
8-lead surface mount package. The MAAM12021
employs a fully monolithic design which eliminates
the need for external tuning networks.
biased using 3 or 5 volt supplies and has an option
for biasing at higher currents for increased dynamic
range.
The MAAM12021 is ideally suited for use where low
noise figure, high gain, high dynamic range and low
power
applications include receiver front ends in the Global
Positioning System (GPS) and Japanese Personal
Digital Cellular (PDC-1500) markets, as well as
standard gain blocks, buffer amps, driver amps and
IF amps in both fixed and portable systems.
M/A-COM’s MAAM12021 is fabricated using a
mature 0.5-micron gate length GaAs process. The
process features full passivation for increased
performance reliability.
