传统固定电源功率放大器的设计流程已经成熟多年。存在明确定义的性能评估指标，放大器设计人员的工作是设计具有最佳性能指标集的功率放大器。这项任务远非简单，但设计师至少了解既定的评估标准。对于包络跟踪功率放大器，情况更加复杂，需要使用更复杂的表征技术。
The process of designing traditional fixed-supply power amplifiers has been well-established for many years. Well-defined metrics for performance assessment exist, and the amplifier designer’s job is to design a power amp with the best set of performance metrics. This task is far from simple, but designers at least understand the well-established assessment criteria. For envelope-tracking power amplifiers, the situation is more complex and requires the use of more sophisticated characterization techniques.
