Description
M/A-COM’s SW-456 is a GaAs monolithic switch in a low cost SC-70 (SOT-363) surface mount plastic package. The SW-456 is ideally suited for applications where very low power consumption, low insertion loss, very small size and low cost are required. Typical application is in dual band systems where switching between small signal components is required such as filter banks, single-band LNA’s, converters, etc. The SW-456 can be used in applications up to 0.25 watts in systems such as cellular, PCS, DCS1800, GSM, CDMA, W-CDMA and other analog/digital wireless communication systems. The SW-456 is fabricated using a mature 0.8 micron GaAs MESFET process. The process features full 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. Proper ESD techniques should be used when handling these devices.
