In this paper we present a technique for obtaining a behavioral model for a power amplifier using a single exponential chirp measurement. The obtained model is equal to the memory polynomial. However, the process relies on a particular excitation that enables orthogonal extraction, making the identification quick and reliable. The model presents good approximation results for different excitations, and can be used for close inspection of the harmonic frequency responses of a power amplifier.
