System analysis and design of mmW mobile backhaul transceiver at 28 GHz

In the next generation of mobile network, 5G, mm-wave (mmW) communication is considered one of the main disruptive technologies to increase data rates and improve spectrum efficiency. Wireless backhaul with stationary or moving nodes is one of the best candidate use-cases. This paper provides a comprehensive analysis on the architecture and design of mmW transceiver with automatic gain control (AGC) for mobility management. The focus is on the RF component requirements, especially, power amplifiers, low-noise amplifier and antennas as well as on their impact on the link-budget. Results are provided based on real figures of commercial components.
