Abstract:
A switch comprising,a MEMS substrate, a diaphragm suspended from and attached to the substrate, the diaphragm being suspended equilaterally from the MEMS substrate, a bridge disposed on the diaphragm, the diaphragm being flexible to move the bridge up and down, a plurality of equilaterally displaced electrodes surrounding the bridge, the electrodes are controlled by controlling voltages to provide electrostatic forces for flexibly moving the diaphragm up and down to move the bridge up and down, an RF substrate bonded to MEMS substrate for encapsulating the diaphragm, and a center waveguide comprising a front center waveguide and a back center waveguide separate by a gap and disposed on the RF substrate, the bridge serving to couple the front center waveguide to the back center waveguide when the diaphragm is actuated to bring the bridge down towards the gap and serving to decouple the front center waveguide from the back center waveguide when the diaphragm is actuated to bring the bridge up away from the gap.
