Description
M/A-COM’s MAAVSS0005 is a GaAs MMIC voltage
variable absorptive attenuator in a lead-free
SOT-143 4-lead surface mount plastic package.
The MAAVSS0005 is ideally suited for use where
attenuation fine tuning, fast switching and very low
power consumption are required.
Typical applications include radio, cellular, GPS
equipment and other automatic gain/level control
circuits.
The MAAVSS0005 is fabricated with a monolithic
GaAs MMIC using a mature 1 micron process. The
process features full chip passivation for increased
performance and reliability.

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.
