Description
M/A-COM’s MAATSS0018 is a 1 bit, 10 dB step
GaAs MMIC digital attenuator in a lead-free SOT-25
surface mount plastic package. The MAATSS0018
is ideally suited for use where high accuracy, very
low power consumption and low intermodulation
products are required. Typical applications include
radio, wireless LANs, GPS equipment and other
gain/level control circuits.

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.
