Prototyping a LTE-A Base Station with a Universal Hardware Platform

This paper presents a universal SDR development platform for prototyping LTE base stations for private networks with a standard-defined front-end operating in the 3.6÷3.8 GHz band with time duplexing. The high power amplifier efficiency of 35% was obtained using a Doherty architecture with a peak power of 160 W at 9.8 dB of PAPR during the LTE20 ETM1.1 waveform test.
