Özet:

Oscillators play an important role in transmitters and receivers. In these systems, stable frequency source and low phase noise are critical for system performance. In radio frequencies, phase locked dielectric resonator oscillators are one of the best options in terms of cost, dimension, and performance. These oscillators are widely used in systems such as RADAR, electronic warfare, and communication. In this thesis, design methodology of phase locked dielectric resonator oscillator is given, an oscillator at 8 GHz is designed, produced and measured. The oscillator output power at the design frequency is measured to be 13 dBm, and the phase noise drops down to -134 dBc/Hz at 1 MHz offset. This thesis contains the details of the design, simulation, and fabrication procedure of a low phase noise phase locked dielectric resonator oscillator.
