ABSTRACT:
Dielectric resonator stabilized micro-strip oscillators in which micro-strip lines are provided to the first, second and third terminals of the active element for oscillation and in which a dielectric resonator coupled at a predetermined position to one of the micro-strip lines which is not used as an output terminal is disclosed. In the integrated microwave oscillator, there is an active element for oscillation such, for example, as GaAs-FET having first, second and third terminals. Micro-strip lines connect to the first and third terminals, and a micro-strip line connected between the first and third terminals form a feedback circuit, together with the first mentioned micro-strip lines. A dielectric resonator is coupled to one of these micro-strip lines which is not used as an output terminal at a predetermined location.
