摘要

本文提出了一种新的方法来选择最佳的Doherty功率放大器(PA)不对称比，同时考虑了Doherty拓扑限制和晶体管技术的限制。该方法具有Doherty复杂度的可扩展性，并且与技术无关。文中还简要地给出了Doherty的一个实例，该实例支持这种新方法，在测量性能和预测性能之间显示出良好的一致性。

A Novel Approach to Selecting Doherty Amplifier Asymmetry

This work introduces a new method for selecting the optimal Doherty power amplifier (PA) asymmetry ratio considering both the Doherty topology limitations, and the limitations of the transistor technology. The method is scalable with Doherty complexity and is technology agnostic. An example Doherty is also briefly shown which supports this new method, with excellent alignment shown between measured and predicted performance.
