Abstract

A theoretical investigation of the IMPATT diode supply current on the operation mode of a generator is out. As additional parameters affecting the operation mode, the coefficients of signal reflection from the inhomogeneity in the output transmission line and the delay time of this signal have been analyzed. It is shown that the following modes of synchronization may appear at various relations between these parameters: with an instability of the amplitude, multifrequency mode, dynamic chaos mode, single-frequency mode, and oscillation suppression mode. Based on the solution to the autogenerator equation, the possible operation modes of a generator based on the IMPATT diode were analyzed. The results make it possible to assess the range of parameters where a negative effect upon the operation mode of the oscillator will be absent and the ranges of the oscillator’s parameters when the mode of dynamic chaos can be obtained.
