Product Description
Stanford Microdevices SSW-224 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, 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.
