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

Abstract 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

Proof of concept of mmWave high capacity backhaul:RF and antenna components

Abstract In the next generation of mobile network, 5G, mmwave (mmW) communication is considered one of the main disruptive technologies to increase data rates, improve spectrum efficiency and provide new frequency bands for wireless communication. New frequency bands require new radio frequency components and design of radio circuits operating at mmW frequencies is a challenging task. This paper provides simulation and measurement results of a commercial power amplifier, a Wilkinson divider and a distributed element 22 GHz high pass filter used in a proof of concept 5G mmW radio
