Abstract-In this paper an approach for stability analysis of microwave oscillators is proposed. Using the perturbation theory and averaging method, a theorem which relates the oscillation stability to the stability of the periodic average of the circuit's Jacobian is mentioned. Using this theorem, a criterion for oscillation stability is devised. The proposed criterion is applied to the stability analysis of a negative resistance diode oscillators and a Colpitts oscillator. This method is readily applicable to microwave CAD routines.

In this contribution, nonlinear synthesis techniques for microwave circuits are presented. Emphasis is made on their principles, implementation, and applications. Four main types of nonlinear circuit are considered: frequency mixers, oscillators, frequency dividers and frequency multipliers. The operation principles and their main characteristics are introduced, together with the most useful synthesis techniques. Approximate analytic techniques like Volterrra series and the describing funciton are presented, as well as design tools, based on harmonic balance, such as the auxiliary generator, for oscillator and frequency multipliers. Analyses of noise and stability are also carried out. The techniques are illustrated by means of simple but practical FET‐based circuits.
