Dielectric Resonator Oscillator Using the Coupling Between a Coplanar Waveguide( CPW ) and a TE01 δ a Mode Dielectric Resonator

Abstract

In this paper, a series feedback FET DRO (dielectric resonator oscillator) at around 10 GHz developed in GCPW (grounded coplanar waveguide) technology is reported. The DRO is based on coupling between a TE01 delta mode dielectric resonator and a uniform GCPW line. The measurement results of the FET DRO circuit in GCPW are compared with the characteristics of the circuit in microstrip, in terms of output power and phase noise. The GCPW DRO shows better phase noise, but not output power
