This paper describes the design and performance of a dielectric resonator oscillator near 1.3 GHz. Unique features of this oscillator are the very low single side-band phase noise levels achieved, the effectiveness of the vibration isolation system implemented and the parabolic frequency-temperature characteristic attained. A phase noise level of -132 dBc/Hz at 1 kHz offset and a noise floor of -175 dBc/Hz were measured under both quiescent and vibrating conditions. Phase noise data are presented under sinusoidal and random vibration conditions and a vibration sensitivity of 3×10-10/g was measured at 25 Hz vibration frequency. The temperature sensitivity was 0.4 ppm/°C at 60°C, about 7° from the measured turnaround temperature of 67°C
