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.
M/A-COM fabricates the MASWSS0121 using a 1.0-
micron gate length MESFET process. The process
features full chip passivation for performance and
reliability.

these survivability limits.
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.
