摘　　要：微波铁氧体环行器是雷达和微波系统中一个重要的非互易部件。它端口与端口之间的隔离度除与它本身的环行状态有关外 ,还与第三端口外接负载的反射系数有关。用 S参数分析了外接负载对环行器隔离度测量值的影响 ,给出了在测量环行器在不同环行隔离状态时外接负载的选取原则 ,并给出了隔离度测量误差的两个极限范围值。The microwave ferrite circulator is an important non-reciprocal component for radar and microwave system. The isolation at port and port between be differ that in addition to itself circulation state, and yet relate with the reflection-coefficient of external connective load at the three port. This paper uses S parameter to analyse the effect of external connective load on the measurement value of circulator isolation. The selection rule for external connective load at measuring different circulation state of the circulation isolation and the two limitation range values of isolation measurement error are also given.
