S-band T/R module in massive MIMO system for 5G mobile communication

This paper presents a S-band transmitting-receiving (T/R) module in massive MIMO system for 5th generation mobile communication system (5G). The T/R module includes 16 digitalized channels, and it is supposed to operate in TDD mode in sub-6GHz band. Similar to the “tile” T/R module, this Two-Layer-Architecture T/R module is easy to build thin and lightweight massive MIMO system. This module also could be applied in new generation active electronically scanned array (AESA). Brief principles of its operation in massive MIMO system are described.
