Abstract :
In this paper a new approach to the design of nonlinear microwave oscillator is presented which allows optimum large-signal performance of the oscillator to be predicted. The procedure consists in determining a surface including all the combinations of allowed powers available at the terminal ports of the nonlinear device in order to deduce its optimum loads and large-signal efficiency. The technique has been applied to practical diode oscillator circuits. Comparisons with previously published results from the technical literature and with experimental data permit to validate the method
