Abstract
The aim of this paper is to present an easy and rigorous way to design a Doherty power amplifier (DPA) starting from the requirements of the wireless system, in which it has to be integrated. In particular, accounting for the value of the pick to average power ratio (PAPR) of the system, design guidelines will be given to correctly address each design step. The presented design flow will be validated through the realisation of a DPA in GaN technology at 2.14 GHz.
