Description
M/A-COM’s MASWSS0180 is a GaAs MMIC SPDT
terminated switch in a lead-free SOIC 8-lead surface
mount plastic package. The MASWSS0180 is ideally
suited for use where very low power consumption is
required.
Typical applications include transmit/receive switch-
ing, switch matrices, and filter banks in systems
such as radio and cellular equipment, PCM, GPS,
fiber optic modules, and other battery powered radio
equipment.
The MASWSS0180 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.
