Qualcomm QET4100 Envelope Tracker Architecture Analysis

This report presents an architecture analysis of the Qualcomm QET4100 envelope tracker integrated circuit. Since envelope tracking strongly relies on passive components that currently cannot be integrated within the IC package, the analysis also involved the printed circuit board on which the QET4100 was located. This PCB was part of a Samsung mobile handset.
