SSW-524 Datasheet, PDF (1/3 Pages) Stanford Microdevices – DC - 8 GHZ GAAS MMIC SPST SWITCH

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.
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.
