A Digital Envelope Tracking RF Power Amplifier Achieving 400MHz Channel Bandwidth and 91.9% Efficiency for Upper-Mid Band Extreme Massive MIMO 6G Communications
This paper presents a digital envelope tracking supply modulator for upper-mid band extreme massive MIMO 6G communications. The designed series-switches DET IC consists of Buck, SCVD and level selection switches. Cell sliced switches and a power mode selector were applied to improve power back off efficiency. The designed DET IC achieved 91.9% of the peak power efficiency. The DET PA saved larger than 100mW of DC power consumption compared to 5V-fixed-voltage PA for 200MHz RF signal, and it achieved 2.81% EVM and -36.8dBc ACLR at the output power of 17dBm with NR 400MHz.
