A 16-Gb/s millimeter-wave CMOS transmitter with integrated optical receiver for 5G baseband-over-fiber systems

摘要

This paper presents a 65-nm CMOS baseband-over-fiber system-on-a-chip that integrates a 28-32 GHz transmitter with a 16-Gb/s optical receiver. The SoC directly up-convert broadband optical signals to the lower mm-wave band, with an efficiency of 8.6 pJ/bit, for providing backhaul connectivity in 5G base-stations.
