| Abstract: | The design of a 5.305 GHz series feedback free running dielectric resonator oscillator (DRO) is presented. Its simulation and optimization are realized by obtaining the unloaded Q factor of the cavity dielectric resonator (DR) and analyzing the linear and nonlinear models of the DRO. CAD packages of DR_Rez and Agilent Advance Design System (ADS) are used and the best tradeoff among the output power, phase noise, and frequency stability is achieved. With the result of simulation, a physical oscillator prototype is constructed. The measured results show the good agreement with those of simulation. |
