Description
The M/A-COM MASWSS0024 GaAs monolithic switch
provides high isolation in a low-cost, plastic surface
mount package. The MASWSS0024 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 MASWSS0024 using an 0.5-
micron gate length MESFET process. The process
features full chip passivation for performance and
reliability.
Handling Procedures
The following precautions should be observed to avoid
damage:
Static Sensitivity
Gallium arsenide integrated circuits are ESD sensitive
and can be damaged by static electricity. Use proper
ESD precautions when handling these devices.
