Design of the Dielectric Resonator Oscillator with Buffer Amplifier

Abstract:

A new structure of microwave field effect transistor Dielectric Resonator Oscillator (DRO) working at 8.5GHz is presented with negative resistance theory and harmonic balance theory. In order to magnify the output power and enhance the load pulling, a Buffer Amplifier (BA) is designed after the DRO. The nonlinearity and linearity of this structure are analyzed and optimized with commercial software ADS. Then the properties of this structure are simulated with commercial software HFSS. Simulation results show that DRO co-integrated with BA a high output power of 13.426dBm, at an oscillation frequency of 8.5GHz.
