High performance microwave point-to-point link for 5G backhaul with flexible spectrum aggregation

This paper presents a new design of a high capacity PtP microwave system based on SDR and spectrum aggregation techniques, suitable for 5G backhaul scenarios. The system supports data rates up to 4 Gbps with a high degree of agility and flexibility in the carrier frequency, modulation and bandwidth. It uses up to four carriers, occupying a bandwidth of about 480 MHz within 1 GHz IF spectrum. The architecture of digital and analog parts will be presented with experimental results of EVM and PAPR.
