Oscillator applications of double dielectric resonator

Oscillator configurations are presented that are based on a double dielectric resonator structure. A major advantage of this approach is wide, linear tuning of the oscillators. Q-factor degradation associated with metal tuning arrangements is prevented and additional temperature compensation and linearization is possible. The principle of operation and experimental results are shown. Tuning ranges on the order of 20% are theoretically possible. However, careful selection of the oscillator circuit and the active device is required to take full advantage of the double dielectric resonator.<>
