| Abstract: |
| The design and realisation of a C band dielectric resonator oscillator(DRO)is presented.The factors influencing the performance of DRO is discussed.Satisfying results are obtained by adopting some measures of minishing phase noise.At the same time,the optimal coupling microstrip length in the varactor tuning oscillator is deduced based on the equivalent physics model.Excellent results are achieved using computer aided design(CAD)as a tool. |
| Key words: DR DRO phase noise CAD presented. The adopting some in the varactor achieved using |
