Low Cost SOIC 8 Plastic Package
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 passivation for increased performance and reliability.
