Rapid behavior modeling platform for RF power amplifiers/transmitters

This paper presents a rapid modeling platform for RF power amplifiers/transmitters, which consists of the equivalent baseband data acquisition system and the behavior modeling software. The data acquisition system comprises a vector signal generator and a vector signal analyzer to obtain the equivalent baseband output of the power amplifiers/transmitter. The modeling software includes signal generation/acquisition module, modeling module and post-processing module. Different dynamic nonlinear models and a variety of model identification algorithms can be applied to build the forward and reverse model of the power amplifier/transmitter so as to quickly evaluate the linearization performance of a designated power amplifier/transmitter while applying different dynamic nonlinear models.
