(1.35/1.75)
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.
