摘要
介绍了W波段六端口反射计的结构、设计、校正及误差分析.用广义谐振腔的概念优化设计了波导结;对检波器采用多种匹配措施;用比对法校正了该反射计;介绍了一种用最小二乘法测双口网络参数的方法,它具有测试方便,计算简单,精度高的优点;最后对精度作了分析.
The paper describes a W-band six-port reflectometer, including its design,
calibration and error analysis. The waveguide junction is designed optimally by the use of
the concept of generalized resonant cavity. The diode detectors are used as powermeters
which are matched well. The equipment has been calibrated by many methods. For meas-
uring two-port network parameters, a least square method is proposed, which has merits
of easiness, quickness and high accuracy.
