Experimental and computer simulation analysis of a Gunn diode

Bias-voltage and frequency dependencies of large signal electronic admittance of a Gunn diode have been measured systematically in the 8- to 13-GHz frequency range. The results were qualitatively verified by computer simulation. These results furnished information which was useful in the direct design of broad-band injection-locked oscillators and amplifiers. The results also gave a better understanding of irregular phenomena commonly observed in conventional oscillators.
