本文介绍了一类三线平衡机的设计过程。结果表明，三线平衡器可以看作是两个相同耦合器的组合。因此，本文所开发的方法采用具有适当耦合因子的耦合器设计来设计这类平衡器。推导出了三条耦合线的法向模态参数。物理尺寸由这些参数得到。该程序已在两层结构下实现，并与全波电磁仿真和实验测量结果进行了比较验证。
This paper describes a design procedure for a class of three-line baluns. It is shown that the three-line balun can be considered as a combination of two identical couplers. Thus, the method developed here uses the design of couplers with an appropriate coupling factor for designing this class of baluns. The derivation leads to the normal mode parameters for the three coupled lines. Physical dimensions are obtained from these parameters. This procedure has been implemented for two-layer configurations and verified by comparison with results from a full-wave electromagnetic simulation and experimental measurement.
