Abstract :
A YIG (yttrium iron garnet) oscillator tunable over the 3.8-30-GHz band has been developed. The author analyzes the oscillator and discusses those of its properties which are critical for wideband and high-frequency performance. An extension of the oscillator band to fundamental limits was achieved by small signal analysis. In addition, optimization of the nonlinear steady state oscillations is considered. The methods of large signal S-parameters, harmonic balance, averaging, and integral manifolds are compared and rigorously justified.<>
