Description
M/A-COM’s MAAVSS0001 is a GaAs MMIC voltage
variable absorptive attenuator in a lead-free
SOT-25 surface mount plastic package. M/A-COM
fabricates the MAAVSS0001 with a proven
monolithic GaAs 0.5 micron gate process that
features full chip passivation for performance and
reliability.
Applications
The MAAVSS0001 is ideally suited for applications
that require fine tuning, linear attenuation with
voltage, and very low power consumption.
Typical applications for the MAAVSS0001 include
automatic gain control circuits in satellite radio
receivers and other wireless receivers.

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.
