一个高精度和高可靠性的平台对于功率放大器（PA）设计人员评估PA原型的特性以及数字预失真器工程师验证他们的模型和算法至关重要。本文讨论了建立一个高性能的功放特性和预失真（PD）测试平台的数字处理技术。我们还提出了一种新的技术来表征的频率响应的矢量信号发生器和矢量信号分析仪独立，而不使用任何其他仪器。本文中描述的技术非常有用，特别是对于窄带矢量发射机和接收机，以提高其性能。对这些技术进行了实验评估，用于F类PA的表征和PD。测试结果表明，利用该技术可以成功地建立一个高精度、宽带宽的测试床。© 2012 Wiley Periodicals，Inc.

A platform of high accuracy and reliability is crucial for power amplifier (PA) designers to assess the characteristics of the PA prototype, and for the digital predistorter engineers to validate their models and algorithms. Digital processing techniques for building a test bed of high performance for PA characterization and predistortion (PD) are discussed in this article. We also proposed a novel technique to characterize the frequency responses of the vector signal generator and vector signal analyzer independently without using any other instrument. The techniques described in this article are quite useful, especially for narrowband vector transmitters and receivers, to improve their performance. These techniques were experimentally evaluated, both for characterization and PD of a class‐F PA. Test results show that using such techniques can successfully build a test bed of high accuracy and wide bandwidth. © 2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.
