Abstract: A microwave cavity filter is configured for operation in the dual TE22N mode to realize a very high Q factor at very high frequency ranges. The microwave filter is formed from using one or more cylindrical cavities in which two orthogonal field polarizations of the TE22N mode are excited and coupled together by means of a coupling element. Different combinations of inter-cavity irises provide for both direct and cross-coupling of aligned field polarizations in adjacent cavities, as required, to realize complex filter functions. The irises may be formed in either a side or end wall of the cavities for both collinear and planar mount configuration. Negative mode coupling also allows for transmission zeros to be realized on either side of the filter passband.

Abstract: A TE011 cavity filter assembly is disclosed. The system includes at least one resonator operating in TE011 mode having a resonant frequency. The at least one resonator may include a cavity comprising an inner diameter and a cavity length. The at least one resonator may also include a first metal disc inside the cavity. The first metal disc may include a disc diameter and a void in the metal disc, which includes a void diameter and a void depth. The inner diameter of the cavity may be greater than the disc diameter creating a gap with a gap width and a gap depth. The TE011 cavity filter assembly may further include positive coupling.

Abstract: A MEMS electrostatic actuator assembly for connection to a DC voltage supply includes a MEMS device and a capacitive element. The MEMS device has a conductive member and a restoring force element. The conductive member is continuously movable between first and second positions in response to the electrostatic force produced by the DC voltage supply. The restoring force element provides a restoring force to the conductive member to move it back to the first position. The capacitive element is coupled in series between the MEMS device and the DC voltage supply and is used to limit the electrostatic force produced within the MEMS device to a value substantially equal to the maximum restoring force provided by the restoring force element.
