Description
M/A-COM’s MAAMSS0005 is a low current, high
reverse isolation LO buffer amplifier in a low cost
SOT-143 plastic package. The MAAMSS0005 is
ideally suited for LO buffer handset applications in
the Cellular, GPS and PCS frequency bands.
The MAAMSS0005 is fabricated using M/A-COM’s
0.5 micron low noise E/D GaAs MESFET process.
The process features full passivation for increased
performance and reliability. Pin Configuration

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.
