In one form of the invention, a resonant cavity filter (50) is disclosed, comprising an input port (210) for receiving an input signal, a dielectric resonator (204) in a cavity, the dielectric resonator operable to receive an input signal from the input port and further operable to produce an output signal at a resonant frequency of the cavity, an output port (212) operable to receive the output signal and a tuning plate (308) disposed in the cavity, the tuning plate coupled to a control means operable to cause movement of the tuning plate, thereby changing dimensions of the cavity, the control means operable to determine a frequency of the input signal, retrieve an expected tuning plate position from a memory (514) based on the frequency, and move the tuning plate to the expected position. Other systems, devices and methods are disclosed.
