Description
M/A-COM's SW-393 is a GaAs Monolithic SPST terminated
switch in a low cost SOIC 8-lead plastic package. The SW-393
is ideally suited for use where low power consumption and high
isolation are required. Typical applications include PCS and
GSM LO switching, switch matrices and switched filter banks in
systems such as radio and cellular equipment.
The SW-393 is fabricated using a mature 1-micron gate length
GaAs MESFET process. The process features full chip passiva-
tion for increased performance and reliability.
