我们提出了一种结合当前签名和替代测试方法的低成本射频组件测试技术。该技术适用于非侵入式内置测试以及低成本的自动测试设备(ATE)应用。该技术的主要特点是：(1)通过采样电源电流来减少信号路径上的负载；(2)基于系统约束的灵活的测试激励产生；(3)通过使用单个测试激励和数据采集来缩短测试时间；(4)从单个激励中准确地预测所有规格值。使用所提出的实现的两个实验证明了该技术在使用两种不同技术构建的单平衡和双平衡混频器上的精度和效率。
We propose a technique for low-cost testing of radio-frequency components integrating current signatures and alternate test methodology. The technique is suitable for non-invasive built-in test as well as low-cost automated test equipment (ATE) applications. Main features of the technique are (1) minimum loading on signal path by sampling supply current, (2) flexible test stimulus generation based on system constraints, (3) test time reduction by using a single test stimulus and data acquisition, and (4) accurate prediction of all specification values from the single excitation. Two experiments using the proposed implementation demonstrate the accuracy and efficiency of the technique on both single-balanced and double-balanced mixers built with two different technologies.
