Zhancang wangs high efficiency load modulation power amplifiers for wireless communications 9781608079872 17900 reviews the designs of radio frequency high effiency load modulation amplifiers for wireless systems and covers all kinds of details for pa design and optimization that engineers must have. This cutting edge resource presents a complete and systematic overview of the practical design considerations of radio frequency rf high efficiency load modulation power amplifiers pa for modern wireless communications for 4g and beyond. Rf power amplifier efficiency big challenges for designers by barry manz mouser electronics the basic laws of thermodynamics ensure that no electronic device can achieve 100 efficiency although switch mode power supplies come close approaching 98. If high output power is needed from a class a circuit the power supply and accompanying heat becomes significant for every watt delivered to the load the amplifier itself at best uses an extra watt for high power amplifiers this means very large and expensive power supplies and heat sinks.
