本文提出了一种测量放大器与天线间未知负载阻抗失配的简单方法。测量负载阻抗失配的方法包括传输线的截面和沿传输线沿着的适当位置处的电压测量。使用Agilent的ADS软件工具进行仿真，以确定物理尺寸和电路特性。电压传感器采用四象限乘法器AD834，测量分段输电线路上的三点电压。仿真和试验结果表明，与理论预测吻合良好。
This paper presents a simple method for measurement the unknown load impedance mismatch between amplifier and antenna. The method to measure load impedance mismatch consists of sections of transmission line and voltage measurements at appropriate locations along the transmission line. Simulation is performed using Agilent's ADS software tool to determine the physical dimensions and the circuit characteristics. And AD834 quadrant multiplier is used to voltage sensor for measuring the 3-point voltage on sectioned transmission line. Simulation and test results show good agreement with theoretical predictions.
