本文提出了用肖特基低势垒二极管检波器检测功率的六端口测量系统整体校准的新方法。根据六端口相对功率理论即对某一负载各端口相对功率比值不随输入功率变化 ,由最小二乘法得到检波器的特征参数 ,结合四标准法 ,确定六端口网络的系统常数。与拟合校准方法的比较证实了该方法的有效性。测量结果表明 ,该测试系统达到了与采用热敏电阻进行功率检测的测量系统相当的测量精度。 This paper presents a new method for the overall calibration of a six-port measurement system that uses Schottky low-barrier diode detectors to detect power. According to the theory of six-port relative power, that is, the relative power ratio of each port of a certain load does not vary with the input power, the characteristic parameters of the detector are obtained by the least square method, and the system constant of the six-port network is determined by combining four standard methods. The comparison with the fitting calibration method confirms the validity of this method. The measurement results show that the test system achieves a measurement accuracy equivalent to that of a thermistor-based power measurement system.
