Product Description
Stanford Microdevices SSW-524 is a high performance
Gallium Arsenide Field Effect Transistor MMIC switch housed
in a low-cost surface-mountable 8-pin ceramic package.
SSW-524
DC-8 GHz GaAs MMIC
SPST Switch
This single-pole, single-throw, non-reflective switch con-
sumes less than 50uA and operates at -5V and 0V for control
bias. P1db at -5V is +25dBm typical and can be increased to
+28dBm with -8V supply.
The die is fabricated using 0.5 micron FET process with gold
metallization and silicon nitride passivation to achieve
excellent performance and reliability.
