Broad tuning low noise Ku band dielectric resonators oscillators

High performance low phase noise dielectric resonators oscillators are demonstrated incorporating a cascaded SiGe amplifier, a resonator, and a phase shifter. A resonator with enclosure using a dielectric puck is investigated. Very low phase noise is achieved with a performance of -125dBc/Hz at 10kHz offset. This is typically 15-20dB better than most commercial designs.
