摘要
本文提出了一种新型的三线耦合微波平衡器。该平衡器采用三根耦合线之间的宽边耦合和边耦合，结构紧凑，工作频率范围宽。该平衡器的中心频率为2.45 GHz，在FR4印刷电路板上制作，整体尺寸为1.5 mm × 1.2 mm。利用全波电磁模拟器IE3D对原型平衡器进行了仿真。仿真结果与实测结果吻合较好，验证了该平衡器的有效性。
Design of a compact balun with three octant-wavelength coupled lines
A novel microwave balun with three coupled lines is provided in this paper. With broadside coupling and edge coupling among three coupled lines, the proposed balun is compact and a wide operating frequency range is obtained. At a central frequency of 2.45 GHz, this balun is fabricated on the FR4 printed circuit board and with overall size of 1.5 mm × 1.2 mm. The prototypical balun is simulated with the full-wave electromagnetic simulator IE3D. A good match between simulated and measured results validates the proposed balun.
