Nonlinear analysis of synchronized microwave oscillator using Volterra Series

A method to analyse the synchronized microwave oscillators is first developed by use of Volterra Series expansion. The general expressions of calculating responses in harmonic loops are obtained. Some cases such as the frequency divider and doubler are discussed in details. The results show that this method is simpler and can get higher accuracy than the describing function and harmonic balance method, and that it is more efficient than the averaging method
