| The object of this research is to model and build a non-linear dielectric resonator oscillator (DRO) circuit and to develop a CAD based design technique to replace the traditional design approach.;An important problem in the computer-aided design (CAD) of non-linear systems is the steady-state analysis of non-linear microwave circuits. In this thesis, EEsof's Harmonic Balance technique was used to design, simulate and analyze a dielectric resonator oscillator circuit. The technique has significant advantages over traditional design approaches, especially for circuits that required nonlinear optimization to achieve desired goals for frequency, harmonic purity, and power output.;A 3-GHz DRO was designed and fabricated in this thesis. The experimental results are in close agreement with the CAD simulation. |
