SSW-508 Datasheet, PDF (1/2 Pages) Stanford Microdevices – DC-4 GHz GaAs MMIC SPST Switch

Product Description
Stanford Microdevices’ SSW-508 is a high performance
Gallium Arsenide Field Effect Transistor MMIC switch
housed in a low-cost surface-mountable 8-pin small outline
plastic package.
This single-pole, single-throw, non-reflective switch
consumes 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.
