摘要
在介质基板的两侧喷镀铜线构成了平面滤波器的LC单元,铜线的交流电阻对滤波器的高频损耗有重要影响。为优化高频性能,提出了将镀镍的铜线结构代替纯铜导线应用于环形LC单元,即铜上下面镀镍及铜四周镀镍的两种新型导线结构。通过两种新型结构的2D(二维)有限元仿真,提取了不同频率下的交流电阻,分析了后处理结果中集肤效应影响下的电流分布,对比了同频下不同镀镍导线结构的功率损耗,仿真结果验证了镀镍导线结构较普通导线能有效地的提高了对高频信号的衰减能力。
Sprayed copper wires on both sides of the dielectric substrate constitute the LC unit of the planar filter,the AC resistance of copper wires have important impact on high-frequency losses of filter.To improve high frequency performances,nickel-plated copper wire structure instead of copper wire in the ring LC unit is proposed,that using two new types for the nickel plating copper wire structure of up and down both sides and nickel plating around the wire structure.2D(Two-dimension)FE(finite element)simulation of the two new structures were established to extract AC resistance from the different frequencies,and under the influence of the skin effect the current distribution in the results of the post-processing were analyzed.At the same frequency the power losses of different nickel-plated wire structure are compared,simulation results are proved that the nickel-plated wire structure than ordinary wire can effectively increase the ability of attenuation of high-frequency signals.
