摘　　要：铁氧体环行器是移动通信的重要器件之一，他具有单向传输特性，在基站的发射和接收系统中已经被广泛使用。选取比较典型的中心导体为双Y型带线结环行器作为设计对象，工作频段在GSM的接收频段925960MHz，根据设计指标，给出了设计步骤和计算机仿真结果。仿真数据完全满足设计要求和性能指标，这表明经典理论设计与计算机仿真相结合对射频鲒环行器设计有较强的指导素艾．RF ferrite circulator is one of the important devices in mobile communication. It plays an important role in the transmitter and receiver system in the base station, for it has characteristics of simplex transmission. In this article double Y junction as a typical center conductor is chosen, whose working frequency is receiver frequency of GSM, 925 - 960 MHz. According to design goal, design steps and simulation results are presented in detail. The simulation results totally meet the design requirement and specification. It verifies that design theory combined with simulation is intructive in designning RF junction circulator.
