Abstract :
In this paper a method of designing ultra low phase noise Dielectric Resonator Oscillators (DRO) is presented. The design procedure is described basing on an exemplary 1.3 GHz Voltage Controlled DRO realized in the negative resistance oscillator configuration. Issues of the resonator and the active circuit design important for achieving a good phase noise performance are described. Described method was used for designing a 2.85 GHz oscillator with very good results.
