This paper discusses Doherty Power Amplifier(DPA) and its evolution over the years. The basic operational principle of the Doherty amplifier and its defective behavior that has been originated by transistor characteristics will be presented. The different research trends, all aimed to improve the advantages of the Doherty scheme and to solve its inherent drawbacks, are discussed.
