The dataset, used for behavioral modeling and testing, originates from the ITU ML5G-PS-007 benchmark. It includes input and output signals obtained from a nonlinear power amplifier (PA). The input signals feature a wide bandwidth of 200 MHz and vary in average power levels. The output signals captured from the PA exhibit a variety of distortions, encompassing nonlinear effects, short-term memory effects, and most notably, significant long-term memory effects.
