A combined mounting and tuning structure for a dielectric resonator comprised of a stack of a dielectric resonator body, a resilient body of dielectric material and an electrical tuning conductor. A fastening means preferably in the form of a dielectric screw threadedly engaged in a base wall of an enclosure and by turning the fastening means, the tuning conductor is brought closer to the resonator, and the resonant frequency of the resonator is thereby adjusted while also providing a clamping force on the stack so as to maintain its position relative to the base wall. The dielectric resonator tuner of the invention is shown in oscillator and filter circuit embodiments.
