The RF power amplifier is a crucial component in the modern telecommunication system, and it is also the component which consumes the largest portion of energy in the system. With the rapid development of wireless telecommunication techniques, the power consumption of the RF power amplifier has become more and more significant. Therefore, to reduce the power budget and improve the efficiency of the amplifier is an important topic in the future. This thesis aims to focus on the whole family of Class-F RF power amplifiers and present the best performance of the Class-F topology. The family of Class-F amplifiers includes the Conventional mode RF power amplifier and Conventional mode RF inverse power amplifier, the Continuous mode RF power amplifier, and the Continuous mode RF inverse power amplifier.
