Description
M/A-COM’s SW-394 is a GaAs monolithic SPDT
terminated switch in a low cost SOIC 8-lead plastic
package. The SW-394 is ideally suited for use
where low power consumption and high isolation are
required.
Typical applications include transmit/receive
switching, switch matrices and switched filter banks
in systems such as radio and cellular equipment.
The SW-394 is fabricated using a mature 1-micron
gate length GaAs MESFET process. The process
features full chip passivation for increased
performance and reliability.
