Power Consumption and Reduction of High-Power Amplifier in 5G NR Downlink

This article presents a method for estimating the power consumption of radio frequency (RF) power amplifiers (PAs) within the 5G new radio (NR) downlink (from the base station to user equipment), particularly in the absence of user data. We also outline an RF PA design strategy for low power consump...
