Description
M/A-COM's MASWSS0068 is a GaAs PHEMT MMIC single pole double throw (SPDT) switch in a low cost 4 mm FQFP-N 20 lead package. The MASWSS0068 is ideally suited for applications where low control voltage, low insertion loss, high isolation, small size and low cost are required. Typical applications are to replace mechanical relays in CATV systems. This part can be used in all 75 ohm systems operating up to 1.0 GHz. The MASWSS0068 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.

Handling Procedures
Please observe the following precautions to avoid damage:
Gallium arsenide integrated circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Use proper ESD control precautions when handling these devices.
Static Sensitivity
5. The exposed pad centered on the package bottom must be connected to RF and DC ground.
