Abstract :
The signal and noise interaction in microwave amplifiers operating under nonlinear conditions is presented in this paper. The theoretical output noise spectrum calculated from a behavioral modeling based on the autocorrelation function is compared to experimental data obtained from a dedicated test-set. The noise mixing with a sinusoidal signal and its harmonics is then well described for both low-pass and band-pass filtered noise. Moreover, the model is well suited to fit AM-AM characteristics and total harmonic distortion
