Preliminary Preliminary SSW-224 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. DC-6 GHz High Isolation SPDT GaAs MMIC Switch 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.
