This study is carried out considering high PAPR mobile WiMax signals. Due to its high efficiency, the Class E amplifier was chosen. Performances and behavior of the designed amplifier were validated through simulations. In a second time the amplifier was associated to the polar transmitter to analyze the overall performances. Results confirm the challenges of transmitting high PAPR signals. Perspectives encourage the possibilities of providing efficient power amplification using a polar ΣΔ architecture
