Description
M/A-COM’s MAAVSS0008 is a GaAs MMIC voltage
variable absorptive attenuator in a lead-free SOIC-8
surface mount plastic package. The MAAVSS0008
is ideally suited for use where linear attenuation fine
tuning and very low power consumption are
required.
Typical applications include radio, cellular, GPS
equipment and automatic gain/level control circuits.
The MAAVSS0008 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.
