Description
M/A-COM’s MAATSS0020 is a 5-bit, 1-dB step
GaAs MMIC digital attenuator in a lead-free SSOP-
20 surface mount plastic package.
The
MAATSS0020 is ideally suited for use where high
power accuracy, fast switching, very low power
consumption and low intermodulation products are
required at a low cost.
Typical Applications include radio and cellular
equipment, wireless LANS, GPS equipment and
other gain/level control circuits.
The MAATSS0020 is fabricated with a monolithic
GaAs MMIC using a mature 1-micron process.
The process features full chip passivation for in-
creased performance and reliability.

Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be dam-
aged by static electricity. Proper ESD control tech-
niques should be used when handling these de-
vices.
