The influence of load variations on the of autodyne response formation in microwave oscillators under strong reflected emission

On the basis of the developed mathematical model of interaction of the single-circuit microwave oscillator with a strong reflected emission, using numerical methods, the role of load variations on the process of forming the autodyne response is shown. The coefficients of harmonics are calculated as well as amplitudes of harmonic components of the spectrum and levels of average values of load changes depending on a magnitude of the reflection coefficient modulus and changes of its phase. It is established that the main cause of distortions of the autodyne response under the strong reflected emission is the load “non-linearity”. In the case of a weak signal, when the modulus of the reflection coefficient is much lower than one, the load changes are almost harmonic ones and the determinative role in formation of signals with distortions belongs to processes associated with the irregularity of the reflected emission phase incursion.
