Abstract :
In this paper we present the design and performance of a K band DRO (Dielectric Resonator Oscillator). The design incorporates NE71000 MESFET and an open source oscillator topology, which we show to be superior in terms of bandwidth and noise. The same circuit can be used (with different resonators) in the frequency range 21-25 GHz. The output power is 10 dbm, frequency stability 4 ppm/degree C and phase noise -88 dbc/Hz@10 kHz (several db better compared to previously published DROs at this frequency range).
