Abstract :
This paper describes a new approach to modeling RF systems using wavelet transformation. The inherent advantage of this new method is a simulation in both time domain and frequency domain at the same time: some blocks are modeled in the time domain and some models in the frequency domain. An application example is shown for the simulation of a wideband high-power amplifier.
