Application of ET techniques (review of "Envelope Tracking Power Amplifiers for Wireless Communications"; Wang, Z.; 2014)[book/software reviews]

The envelope tracking (ET) approach to power amplifier (PA) design is one way to maximize the energy efficiency of a PA. This book describes the principles of ET operation, signal generation and shaping, design and implementation approaches, and application of ET techniques in the context of RF PAs from basic ET technique principles through their application scenarios.
