Abstract

This paper presents the design of a reconfigurable power amplifier for Mobile WIMAX applications in the user terminal. The amplifier, which operates from 3.4GHz to 3.5GHz, is based on the Doherty technique. This power efficiency enhancement technique is suitable for modern wireless communications systems, as Mobile WIMAX, that present with high peak-to-average power ratio (PAPR) to target high peak data rates while maintaining a trade-off between efficiency and linearity. In addition, reconfigurability in output power levels is added to the design to adapt it to different power scenarios. This work has been carried out in the framework of the CELTIC project MOBILIA, “Mobility Concepts for IMT-Advanced”.
