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.
This paper describes the design of very low noise, tunable, Ku band Dielectric Resonator Oscillators (DROs) presenting phase noise performance of -100 dBc/Hz at 1 kHz offset and -130 dBc/Hz at 10 kHz offset. SiGe based transistors are used for the oscillator sustaining amplifiers which offer circulating power 10 dBm and gain of 4 dB per stage as well as low flicker noise corner between 10 kHz and...
