Analytical tools that characterize nonlinear systems are essential and need to be developed for initial rapid optimizations and understanding of the system performance. Modeling of the input signal is a crucial part of this task. In this work, we present a multi-tone representation for an arbitrary, stochastically not well-defined signal and its application to a feedforward circuit which involve two nonlinear amplifiers, couplers, phase and delay units. Particularly, amplitude and phase aspects of the model are highlighted and verified with RF simulations performed by real power amplifiers and components.
