Datasheet SSW-124 Datasheet (Stanford Microdevices)

Product Description

Stanford Microdevices SSW-124 is a high perfomance
Gallium Arsenide Field Effect Transistor MMIC switch
housed in a low-cost surface-mountable 8-pin ceramic
package.

This single-pole, double-throw, non-reflective switch
consumes less than 50uA and operates at -5V and 0V for
control bias. Its high isolation and low insertion loss, makes
it ideal for T/R switching in analog and digital wireless
communication systems.

The die is fabricated using 0.5 micron FET process with
gold metallization and silicon nitride passivation to achieve
excellent performance and reliability.
