An Analysis of Embedding Impedance for Q-Band Waveguide Gunn Oscillator With Resonance Post

The oscillation frequency tuning range of waveguide Gunn oscillator and its stability depend sensitively on the dimensions of the resonator. Therefore the embedding impedances with the various dimensions of the resonator for Q-band (33~50 GHz) Gunn oscillator are calculated by using HFSS (High Frequ...
