This letter reports a magnetically actuated latching RF waveguide membrane switch. Two distinct cantilever geometries have been investigated by simulations and measurements done in the X-band: one in a leaky waveguide antenna that demonstrates the switchability feature, and the other in a closed rectangular waveguide that provides switched notch-filtering capability. Both switches consume no dc power in their steady states and have switching times of 3 and 80 ms for an applied magnetic field of 12 mT.
