摘要

本文提出了一种充分利用微细线与基片集成波导之间通过耦合槽垂直过渡的宽带平衡器。所设计的平衡器工作在毫米波(mm-Wave)频率，不需要像单片或混合集成电路设计中经常使用的马尔尚平衡器那样的紧密耦合部件。该平衡由两个基片和一个电场过渡组成，通过耦合槽实现平衡端口的180°相移。仿真结果表明，该设计在18.7 GHz ~ 32 GHz范围内可轻松获得53%的FBW，且非平衡端口的回波损耗大于10 dB。仿真结果表明，两个平衡口之间的幅值不平衡和相位差分别小于0.3 dB和±2°。

A Wideband Millimeter-Wave Balun Using Substrate Integrated Waveguide (SIW)

A wideband balun is presented in this letter which makes full use of the vertical transition between microstip line and substrate integrated waveguide (SIW) through a coupling slot. The designed balun operates at millimeter-wave (mm-Wave) frequencies and does not need tight coupling part like Marchand baluns as frequently used in monolithic or hybrid integrated circuit design. This balun consists of two substrates, and an electric field transition through coupling slot achieving a 180° phase shift for the balanced ports. Proposed designed is validated by simulation and could easily obtain a FBW of 53% from 18.7 GHz to 32 GHz with larger than 10 dB return loss at the unbalanced port. Simulated results show that the excellent amplitude imbalance and phase difference between two balanced ports are less than 0.3 dB and ±2°, respectively.
