Description

M/A-COM’s MAAVSS0004 is a GaAs MMIC voltage

variable absorptive attenuator in a low cost SOIC

14-lead surface mount plastic package. The

MAAVSS0004 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 MAAVSS0004 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.
