In this paper Zhu's generalized sampling theorem for sampling of the output signal of a nonlinear system is applied to the case of radio frequency power amplifier modeling. The paper deals in some detail with hardware implementational issues in order to optimize the hardware design in order to make full use of the benefits given by Zhu's generalized sampling theorem. It is shown that some design changes have to be done compared to more traditional receiver designs, such as removing the anti-aliasing filters. It is also shown that the behavioral ampler models that are extracted using data taken using Zhu's generalized sampling theorem have equal or better performance with regard to out-of-band spectral emissions than when the models are extracted using data taken using Nyquist sampling of the output signal of the amplifier.
