High-Efficiency Power Amplifier
Artikel i vetenskaplig tidskrift, 2011

P As are usually the most powerconsuming circuit blocks in wireless communication systems. The overall power efficiency of the system is therefore highly dependent on the PA efficiency. The maximum achievable PA efficiency is determined by the RF power transistor technology as well as the external circuitry, which makes the transistor operate in a certain class of operation. Various high-efficiency classes, including switched-mode and harmonically tuned classes, have been proposed in the literature to achieve theoretical efficiencies of up to 100%. © 2011 IEEE.
