摘要
嵌入式系统中高频信号往往会出现衰减的状况,对于提高滤波装置高频损耗的作用和影响十分有限,使整体系统性能变差。为此,提出嵌入式系统中LC单元导线对其衰减高频信号性能的影响研究。分析不同导线参数对高频损耗的不同影响,并选取最优参数;提取各频段下的导线交流电阻,分析环形LC单元导线镀镍处理后对电流分布、导线功率损耗的影响程度,及对衰减高频信号性能的影响效果。实验证明,对环形LC单元导线镀镍处理后,能够显著改善其对高频信号的衰减能力,提高滤波装置的性能。
The high frequency signal in embedded systems tend to decay,to improve the effect and influence of filter loss at high frequency is very limited,so that the overall system performance becomes worse. Therefore,the influence of LC unit wire embedded system on the attenuation performance of high frequency signal. Analysis of the different effects of different parameters on the wire loss at high frequency,and select the optimal extraction parameters; AC resistance of each frequency band of the distribution of the current analysis of circular LC unit lead nickel plating,influence of wire and power loss of the high frequency signal attenuation performance impacts. The experimental results show that the annular LC unit lead nickel plating processing,can display The attenuation ability of the high frequency signal is improved and the performance of the filter is improved.
