Abstract
An embodiment of the present invention provides a voltage-controlled tunable filter, comprising a tunable ridged waveguide filter formed from a first ridged waveguide cavity coupled to a second ridged waveguide cavity thereby forming a resonator; and one or more tunable capacitors in at least one of said first or second waveguide cavity. The coupling between said first ridged waveguide and said second ridged waveguide may be via a coupling iris or ridged post and the one or more tunable capacitors may comprise a low loss tunable dielectric material and metallic electrodes with predetermined shape, size, and distance. In an embodiment of the present invention the one or more tunable capacitors may be MEMS tunable capacitors that are either parallel plate or interdigital topology. The tunable ridged waveguide filter may be formed from two or more ridged-waveguide resonators and may include an RF Input and RF output connected to the resonator and may be direct coupling probes that are either electric or magnetic. Further, the RF input and RF output proximity coupling may be either electric or magnetic. The inter-cavity coupling may be controlled by the distance and area of the ridged posts.
