ABSTRACT:
A cross-coupled dielectric resonator circuit. Resonator circuits in accordance with the invention may be used to build low-loss compact filters, oscillators, and other circuits, particularly microwave circuits. The resonators are arranged relatively to each other within an enclosure in a very efficient and compact design that enhances adjustability and coupling between adjacent resonators and the cross-coupling of alternate resonators.
