          |  |  Virtually every RF circuit or system design incorporates semiconductor devices such as mixers, diodes, switches, and amplifiers. To some extent, all of these devices exhibit nonlinear current-versus-voltage (I-V) characteristics. The effects of this nonlinearity in the frequency domain can be obtained by applying Fourier transformation to derive the device's power spectral density. This method was applied to a basic p-n junction diode using the Fourier-transform (FT) capability incorporated in the Mathematica software package from Wolfram Research (Champaign, IL).
