Nonlinear signals distortions
in stabilized autodyne microwave oscillators

Noskov V. Ya., Ignatkov K. A., Smolskiy S. M.

The analysis of nonlinear distortions of signals in autodyne microwave oscillators stabilized by external high-Q resonator has been performed. Connection between the basic operating and stabilizing resonators is structurally executed according to the scheme of the low-and-high-pass filter with resistive coupling. The new type of nonlinear distortions of autodyne signal, caused by a frequency dispersion of oscillatory system of stabilized autodyne is revealed. Experimental investigations of the hybrid-integrated oscillator on the 8-mm Gunn diode have confirmed results of theoretical researches.
