US Classification:

333186, 29825

Abstract:

A MEMS mixer filter including an array of a multiplicity of resonator elements with conductive outer surfaces in a coplanar rectangularly tiled array, and two sets of DC bias lines in which alternating resonator elements in each row and column are connected to one or the other sets of bias lines so that laterally adjacent resonators may be biased to a DC potential. The resonator elements are uniform in size and shape. Lateral dimensions of the resonator elements are between 5 and 50 microns. The resonator elements are between 100 nanometers and 100 microns thick, and adjacent resonator elements are separated by a gap between 100 and 500 nanometers. A process of forming the MEMS mixer filter.

International Classification:

B81B 3/00

US Classification:

200181

Abstract:

A MEMS electrostatic actuator includes a bottom plate affixed to a substrate and a top plate suspended above the bottom plate. The top plate has a parallel plate center section and two rotating members electrically connected to the center section. Each rotating member is attached centrally of the rotating member for rotation about an axis of rotation to a set of anchor posts. The attachment includes at least one pair of torsional springs attached along each axis, each spring comprising a rectangular metal square that twists as the rotational members rotate. Electrostatic pull-down electrodes are underneath each rotational member.
