Description
The M/A-COM MASWSS0121 GaAs monolithic
switch provides high isolation in a low-cost, lead-free
plastic surface mount package. The MASWSS0121
is ideal for applications across a broad range of
frequencies including synthesizer switching,
transmit / receive switching, switch matrices and
filter banks in systems such as radio and cellular
equipment, PCS, GPS, and fiber optic modules.

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.
