Abstract :
Dependence of performance of a Gunn Doppler self-oscillating mixer on the oscillator loaded quality factor, bias voltage and bias circuit resistance is investigated theoretically and experimentally. The analysis is based on consideration of stability principle and average voltage-current characteristic of a Gunn oscillator. Location of the operating point of the best performance of a Gunn Doppler self-oscillating mixer is defined. Results of the work can be used for tuning a Gunn Doppler self-oscillating mixer
