This paper aims on three different behavioral models with memory for radio frequency power amplifiers. These models are based on the principle of Volterra series, which were simulated in the Matlab-Simulink environment and implemented on a DSP-FPGA Altera Stratix III board. The MPM, Hammerstein and Wiener models were compared based on the distortion curves AM-AM and AM-PM of a RF-PA 10W through different levels of nonlinearity and memory depth. The results show the metric NMSE in the range of -30 dB for the three models of a NXP 10W GaN HEMT @ 3.0 GHz PA demonstrating its high accuracy during the FPGA implementation.
