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.
