Scientific paper

A type of oscillator composed of a Dielectric Resonator (DR), which is part of a Microwave Integrated Circuit (MIC), is presented. For this oscillator, the oscillating characteristics can be controlled by several parameters, such as the dimensions, the position of the DR in its environment, and the bias voltage of the oscillator. With this technique, a frequency stability sigma(sub y)(tau) of less than 5 times 10 to the minus 9th power for tau = 1s, an output power of 17 dBm and phase noise as low as -106 dBc at 1kHz from the carrier in the 800-1000 MHz frequency band are obtained.
