Abstract

The Bessel-Fourier model is one of the state-of-the-art memoryless power amplifier (PA) behavioural methods that enables fast convergence while accurately captures both amplitude-to-amplitude modulation (AM/AM) and amplitude-to-phase modulation (AM/PM) distortions. This paper presents original propositions for extrapolating the power sweep measurements in order to capture operating scenarios that reach beyond the device characterization. By means of numerical and experimental results we demonstrate that our proposition enables estimating the nonlinear behaviour of the PA at the highest power levels of its AM/AM and AM/PM measurements. Additional original elements of the paper include first reported studies relating to the convergence of the method as well as the first report of experimental verification of the technique for scenarios more complex than two-tone tests.
