M/A-COM's SW-137 is a GaAs MMIC SPDT reflective switch
with an integral Silicon ASIC driver. This device is in a 14-lead
DIP package. These switches offer high intercept points
over a wide bandwidth of operation, while maintaining low
DC power dissipation. These switches exhibit excellent performance and repeatability from 0.01 to 3.0 GHz. The SW-137
is ideally suited for RF/IF communications applications.
