Da. Robertson et al., SEMI-CHAOTIC PULSE EFFECTS IN SELF-MODULATING GUNN OSCILLATORS, International journal of infrared and millimeter waves, 15(3), 1994, pp. 493-503
Self-modulation behaviour has been observed in GaAs Gunn oscillators o
perating at W-band, leading to nanosecond pulses of relatively high pe
ak power. Pulse repetition rates and pulse-widths can be varied reprod
ucibly as a function of bias voltage and bias line termination, and th
ere is evidence for semi-chaotic behaviour in certain regimes.
