This paper addresses the critical weakness of the conventional Doherty Power Amplifier when targeting wideband and deep back-off operation. A load modulation network with a good trade-off between complexity and performance enhancement is proposed for broadband operation around 9-dB back-off. As an initial assessment, its effectiveness in enhancing the performance in broadband operation has been proven using linear simulations.

Abstract

This paper addresses the critical weakness of the conventional Doherty Power Amplifier when targeting wideband and deep back-off operation. A load modulation network with a good trade-off between complexity and performance enhancement is proposed for broadband operation around 9-dB back-off. As an initial assessment, its effectiveness in enhancing the performance in broadband operation has been proven using linear simulations.
