Description
The M/A-COM SW-475 GaAs monolithic switch provides
high isolation in a low-cost, plastic surface mount package.
The SW -475 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 SW-475 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.
