摘要

单段耦合器是窄带器件，因此为了拓宽有用带宽，采用了三段耦合器。本文采用两个三段耦合器组成的系统来构造一个六端口反射计。对所实现的六端口反射计进行了标定，并用于测量不同的未知复端。发现六端口反射计的结果与矢量网络分析仪(HP-8510C)的测量结果非常吻合，在频率范围(2.4-4.4 GHz)内，误差不超过4%的幅度和4/spl度/相位。

Six-port reflectometer realization using two microstrip three-section couplers

The single-section couplers are narrow band devices, so in order to broaden the useful bandwidth, three-section couplers are used. In this paper a system of two of three-section couplers is used to construct a six-port reflectometer. The realized six-port reflectometer is calibrated and used to measure different unknown complex terminations. The results of the six-port reflectometer is found to be in good agreement with the measurements of the vector network analyzer (HP-8510C) with an error not exceeding 4% in magnitude and 4/spl deg/ in phase in the frequency range (2.4-4.4 GHz).
