Abstract

In order to improve the phase noise and the temperature stability of a dielectric resonator oscillator, the cylindrical dielectric resonator which is important for the oscillation frequency is mounted on the substrate standing on its curved surface rather than lying on its end face, as conventionally customary. It is coupled to the RF lines in a higher mode (TM.sub.xxx mode) rather than in the fundamental mode (TE.sub.01.delta. mode).
