M/A-COM’s MAAM12000-A1 is a wide band, low
noise, MMIC amplifier housed in a lead-free, small
8-lead ceramic package. It includes two integrated
gain stages and employs series inductive feedback
to obtain excellent noise figure and a good, 50-ohm,
input and output impedance match over the 1.2 to

The MAAM12000-A1 is ideally suited to receivers in
GPS and DGPS applications and operates over both
the L1 and L2 frequency bands. Because of its wide
bandwidth, the MAAM12000-A1 can also be used as
a driver, buffer or IF amplifier in numerous
commercial and government system applications
that require high gain, excellent linearity and low
power consumption.
