Description
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
1.75 GHz band.
The MAAM12000-A1 is fully
monolithic, requires no external components and is
provided in a low-cost, user-friendly, microwave
package.
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.
The MAAM12000-A1 is manufactured in-house
using a reliable, 0.5 micron, GaAs MESFET process.
This product is 100% RF tested to ensure
compliance to performance specifications.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
Operating The MAAM12000-A1
Nominal bias is obtained by connecting -5 volts to
pin 4 (V
GG
) followed by connecting +5 volts to pin 5
(V
DD
). Note sequence.
Power down in reverse sequence.
