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.
