Simulation model of the transmission path for 5G NR base station

Abstract: The article presents the results of modeling an analog radio path of a fifth-generation cellular base station in the NI AWR Design Environment. The validation of the power amplifier model was performed in the AWR software environment. The validation is based on the comparison of measurement results for the nonlinear parameters of the amplitude characteristics of the microwave amplifier obtained on the amplifier model, with the results obtained during mathematical modeling of the nonlinear amplifier. The results of measuring the vector magnitude error between the input and output signals in the radiopath model are presented.

Keywords: 5g, microwave amplifier, error vector magnitude, intermodulation distortion, analog radiopath
