The present invention is a system and a method of filtering a signal at a receiver, the signal having at least a desired channel and blockers. A first converter converts a first copy of the signal resulting in a relatively narrow band, high-resolution first signal. A second converter converts a second copy of the signal resulting in a relatively wide band, low-resolution second signal. Once each copy of the signal is converted, the copies are passed to a combiner. At the combiner, the two copies of the signal are analyzed and the desired channel is extracted from the first copy of the signal by removing any inter-modulation product caused by any interference detected in the second copy from the blockers (not detected in the first copy).

In accordance with principles of the present invention, a two or more pole dielectric resonator circuit is provided with resonators that are elliptical in cross section orthogonal to the longitudinal axis. The resonators are mounted so that they are rotatable about their longitudinal axes, such that the straight line distance between two adjacent resonators measured in a straight line between orthogonal to and intersecting the longitudinal axes of the two resonators is a function of the orientation of the resonators about their longitudinal axes. The resonators can be oriented about their longitudinal axes in any orientation to adjust their spacing, which is directly proportional to their coupling magnitude, which, in turn, is proportional to the bandwidth of the circuit.
