摘要:
本文提出了一种基于LTCC技术的集总巴伦的设计与实现方法。该小型化集总巴伦由简易LC巴伦结构改进而成，利用ADS软件进行电路仿真以及HFSS软件三维建模设计。性能测试结果表明：测量结果数据与仿真结果基本一致，该巴伦的标称中心频率为70 MHz，频带宽20 MHz，通带内插入损耗小于4.7 dB，两端口相位差大于172˚，尺寸仅为2.5 mm × 1.5 mm × 1 mm。完全能够满足当今通信设备日益小型化的要求。
This paper presented a design and realization method of lumped balun based on the LTCC tech-nology, which was derived from simple LC balun and designed by ADS circuit simulation and the HFSS software to optimize the 3D modeling. The measured results agree with the simulated data basically, the center frequency of balun sample is 70 MHz, the bandwidth is 20 MHz, the insertion loss of the pass band is less than 4.7 dB, the phase difference between the two output ports is more than 172˚, the size is only 2.5 mm × 1.5 mm × 1 mm. The balun can totally be used in miniaturized mobile communication equipment.
