A Dual Load-Modulated Doherty Power Amplifier Design Method for Improving Power Back-Off Efficiency

In this paper, the load modulation process of a Doherty power amplifier (DPA) is analyzed to address the issue of why designed DPAs have a very low efficiency in the back-off state in some cases. A general formula of the real load modulation process is also given for analyzing the load modulation of...
