Description

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 per-

formance and repeatability from 0.01 to 3.0 GHz. The SW-137

is ideally suited for RF/IF communications applications.
