The research in this work focuses on systematic design procedures for efficient broadband Doherty power amplifiers. The 2.6 GHz band (2500 - 2690 MHz) is unique so far as it includes a substantial spectrum in all three international Telegraph Union (ITU) regions for terrestrial mobile communications. It is considered as the band most appropriate for 3G/4G wireless communication. Therefore, 2.6 GHz is selected as the center of frequency for the demonstrators developed in this work.
