摘　　要：随着毫米波雷达在自动驾驶、机场异物探测等领域的应用,(92~96) GHz频段(W波段)功率放大器的性能评价备受关注。为解决该频段功率放大器的测试问题,给出了一种基于功放集成型大功率网分扩频的测试方案。该方案采用专用网分扩频模块,该模块具备网分扩频和信号功率放大两项功能,可实现在一套测量系统中完成全部功率参数和小信号S参数的测量。与传统测量方式相比较,具有系统集成度高、测量连接方式简单、测试效率高、测量重复性好等特点。通过试验验证,所提出方法可有效解决W频段功率放大器的测试任务,并显著提高功率放大器的测试效率。With the application of millimeter wave radar in auto pilot, FOD detection and other fields, the performance of(92~96) GHz(W-band) PA has attracted much attention. In order to solve the measurement of W-band PA, the paper presents a test scheme based on high-power frequency extender of VNA. Compared with other extenders, the high-power extender contains a build-in PA. The scheme can complete the measurement of all parameters in one measurement system. Compared with the traditional measurement of power parameters and small signal S parameters, it has the advantages of high system integration, simple measurement connection, one-time calibration to achieve all parameters measurement. It also can improve the repeatability of measurement. The paper presents the principle diagram of measurement setup, measurement procedure and some tips for measurement.
