Abstract :
A theoretical investigation into intermodulation products resulting from multiple equal strength signals fed into a nonlinear amplifier is presented and a comparison made with measured data. An analytical form is given for the output when the level of AM-PM conversion is small. Otherwise, a numerical analysis involving the discrete Fourier transform is employed
