The high peak-average modulation formats supporting high speed 4G wireless data pose a significant challenge to power amplifier design. This presentation highlights the subtle system differences between Polar modulation, EER, envelope following and state-of-the-art Envelope tracking. The discussion then moves to examine the challenges of power amplifier design related to high bandwidth supply modulation. Topics include amplifier supply decoupling, multi-stage modulation, noise and stability.
