ABSTRACT:
The invention is an apparatus and technique for tuning the cross coupling of resonators in a dielectric resonator circuit. A cross coupling element such as a coaxial cable having a first end positioned adjacent a first resonator in the circuit and a second end position adjacent a second resonator is supported on the housing of the circuit intermediate its first and second ends. At least one end of the cross coupling element is in contact with a cross coupling tuning element that extends through an external wall of the housing so that it can be manipulated from outside of the housing to move the corresponding end of the cross coupling element relative to the adjacent resonator inside the housing without opening the housing.
