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.

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： A voltage tunable dielectric varactor includes a substrate having a low dielectric constant and having generally planar surface, a tunable ferroelectric layer positioned on the generally planar surface of the substrate, and first and second electrodes positioned on a surface of the tunable ferroelectric layer opposite the generally planar surface of the substrate. The first and second electrodes are separated to form a gap therebetween. The varactor includes an input for receiving a radio frequency signal and an output for delivering the radio frequency signal. A bias voltage applied to the electrodes changes the capacitance of the varactor between the input and output thereof. Phase shifters and filters that include the varactor are also described.
