Description
The M/A-COM MAATSS0019 is a 4 Bit, 1 dB step
GaAs MMIC digital attenuator in a lead-free TSSOP16 surface mount plastic package.
The
MAATSS0019 is ideally suited for use where high
accuracy, very low power consumption and low
intermodulation products are required.
Typical
applications include radio, cellular, wireless LANs,
GPS equipment and other gain / level control
circuits.
The MAATSS0019 is fabricated using a mature 1
micron GaAs MESFET 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.
