  Abstract

This paper introduces a 5G mobile communication test bench implementation aimed at inter-industry convergence. For the hardware based 5G test bench configuration, we first describe the development of a frequency up and down converter for generating 28GHz RF signal. The developed frequency up and down converter provides a function to convert a 5G IF signal made at 6GHz or lower to a 28GHz RF signal and again convert a 28GHz RF signal to a 3GHz band IF signal. The developed frequency up and down converter provides frequency flatness within 2 dB in the 1 GHz frequency span. The test results were verified using a 5G 1GHz signal. In addition, using the baseband simulator provided by NI (National Instrument), the NR signal was interlinked with the developed frequency up and down converter. Using the hardware based 5G test bench, the NR signal generated at 3GHz or less is converted into a 28GHz RF signal, transmitted through the horn antenna, and the 28GHz RF signal transmitted through the receive horn antenna is converted back to 3GHz or less respectively.
