Abstract
This work presents a large-signal time-domain behavioral model of an off-the-shelf RF amplifier based on QPSK-like multisine measurements. The multisine has been designed using an automated procedure. As a result, the excitation's Probabiity Density Function (PDF) approximates that of a realistic QPSK-modulated digital signal. The model accurately predicts both amplitude and phase of the complex envelope around the carrier as well as higher harmonics.Proceedings Title
