Abstract :
In this paper, a novel Gunn diode push-push oscillator is proposed. Two Gunn diodes and a coplanar waveguide resonator are used for the oscillator. The combination is considered to be an active resonator. The Gunn diodes are arranged at both ends of the resonator. The magnetic field at the both ends of resonator is coupled with the output circuit. The measured output power is +3.67 dBm at 19.8 GHz. The phase noise is -115.2 dBc/Hz at 1 MHz offset frequency. The oscillator is designed easily and achieves low phase noise performance with low cost by using the advantage of Gunn diode
