Abstract
A microwave resonator operating in the TE.sub.11 circular mode with a pair of iris plates defining the resonator, each iris including an elliptical aperture centrally disposed therein, the resonator having a rotary joint midway between the irises at the location of a current null so that the two half portions of the resonator may be rotated with respect to each other in order to provide a desired relative iris axis alignment for an infinitely variable coupling value between a minimum value determined by the minor axis dimension of the elliptical apertures and a maximum value determined by the major axis dimension thereof.
