摘要： An embodiment of the present invention provides a voltage-controlled tunable filter, comprising a tunable ridged waveguide filter (300) formed from a first ridged waveguide cavity coupled to a second ridged waveguide cavity thereby forming a resonator; and one or more tunable capacitors (310, 320) 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.

摘要： An embodiment of the present invention further provides an apparatus capable of reducing selected signal components in a communication link comprising a signal line conveying a communication signal including a desired signal component and at least one undesired signal component; a first signal loop coupled to the first signal line capable of generating a signal such that when combined with the first signal line reduces a first of the at least one undesired signal components; and a second signal loop coupled to the first signal line capable of generating a signal such that when combined with the first signal line reduces a second of the at least one undesired signal components. The first signal loop may include a tunable delay enabling the generation of the signal that when combined with the first signal line reduces a first of the at least one undesired signal components. Further, the second signal loop may include a tunable delay enabling the generation of the signal that when combined with the first signal line reduces a second of the at least one undesired signal components. The first of the at least one undesired signal components may be intermodulation distortion and the adding of a signal generated by the first signal loop may reduce or eliminate it. Further, a second of the at least one undesired signal components may be receive signal distortion and the adding of a signal generated by the second signal loop may reduce or eliminate it.
