20 MHz Bandwidth Envelope Tracking Power Supply Using eGaN FETs

This article presents an envelope tracking power supply using EPC8004 high frequency eGaN® FETs for 4G LTE wireless base station infrastructure. An ET power supply with four-phase soft-switching buck converter using eGaN FETs is able to accurately track a 20 MHz 7 db PAPR LTE envelope signal with greater than 92% total efficiency, delivering 60 W average power. The design is scalable to satisfy different power levels by choosing different eGaN FETs.
