POWER AMPLIFIER WITH IMPROVED POWER EFFICIENCY

摘要

Provided is a power amplifier used in a transmitter of a communication system. The power amplifier may include a power amplifier module to amplify power of a transmitting signal, an energy converter module to receive thermal energy generated by the power amplifier module and to convert the received thermal energy into electric energy, and a direct current (DC)-DC converter module to produce DC power using the electric energy generated by the energy converter module and to supply the produced DC power to the power amplifier module.
