    简化附加功率效率测试使用一台 8990B 峰值功率分析仪-应用说明

    简化附加功率效率测试使用一台 8990B 峰值功率分析仪-应用说明

    Show Description

    附加功率效率(PAE)概述

    与 S 参数、1 dB 压缩点和 IP3 等其他测量工作一样,附加功率效率PAE 是一种典型的功率放大器(PA) 测量操作。这些测量工作通常在集成电路 (IC) 开发阶段、故障排除、质量保证验证或生产测试期间实施。

    附加功率效率PAE 是衡量功率放大器功率转换效率的一个指标。它以效率百分比的形式,说明有多少直流功率在功率放大器中转换为射频功率。理论上,输送给放大器的所有功率都将转换为输出功率。但事实并非如此,因为一定数量的直流功率会以发热的形式损失掉。射频功率放大器的 PAE 规格会因放大器的设计和类别不同而异。

    大多数附加功率效率(PAE) 测试设置都会使用多台仪器来测量射频、电压和电流。例如,测量期间可能需要使用射频功率表或带二极管检测仪的数字示波器 (DSO),以便确定射频功率,同时使用数字万用表 (DMM) 或直流功率分析仪来测量电压和电流。某些高级测试案例还使用了 Keysight网络分析仪。测试操作员需要通过远程程序检索测量数据,而不是直接在测试仪器上查看测量数据。

    Keysight 8990B 峰值功率分析仪提供了另一种设置方案,允许在一台仪器上开展附加功率效率测试工作。通过此应用文章,您将了解峰值功率分析仪操作简单直接,不仅可以测量附加功率效率 (PAE),还可以查看被测功率放大器的瞬时射频包络和直流功率。
