Resonant circuits using Gunn diodes
A. Spasov, R. I. KOZHUKHAROV · International Journal of Electronics · 1978
The paper deals with some special features of Gunn diode operation in a resonant circuit, which arise from the non-linear characteristics of the diode's complex impedance. Autonomous and non-autonomous modes of operation for Gunn diode oscillators are discussed. The considerable influence that the non-linearity of the Gunn diode's domain capacitanee has on the operation of such systems is shown. Parametric phenomena caused by this non-linearity are examined. The method used allows a complete study of such systems by comparatively simple but correct treatment of the problems. The results obtained can be successfully used in the study of resonant circuits with microwave transistors, IMPATT diodes and Josephson junctions. All the results are experimentally proved.
