Abstract
A cavity resonator having a coupling iris (3) has an auxiliary iris (5) which divides the resonator (1) into a coupling space (8) and a resonator space (9). Thus, the auxiliary iris (5) alters the length effective for the resonant frequency of the resonator (1). Disturbances, particularly temperature-induced deformations of the coupling iris (3), may thereby be effectively compensated.
