摘　　要：高频继电器信号路径的分布参数是影响继电器射频(RF)性能的主要因素。通过对基于分布参数的等效电路进行分析,可以优化继电器RF性能,而分布参数的准确提取是正确建立等效电路的基础。本文对于高频继电器信号路径的均匀区域应用经典传输线理论进行分布参数提取,对于尺寸突变、结构不连续等非均匀区域应用部分元等效电路(PEEC)等方法进行提取,得到了完整信号路径的分布电容、电感、电阻值。对基于分布参数的等效电路进行仿真,得到了继电器插入损耗及电压驻波比(VSWR)曲线。The distributed parameters of signal path of high frequency relay are the main factors that influence the radio frequency （RF） performances of relay. The RF performances can be optimized through analysis of the equivalent circuit based on distributed parameters of signal path, and the precise extraction of parameters is the basis of building up the circuit. In this paper, the classical transmission line theory is used to extract the distributed parameters of uniform signal path of relay while the partial element equivalent circuit （PEEC） method is used to extract those of signal path with discontinuities. Thus the distributed capacitance, inductance and resistance of the whole signal path are obtained, based on which the equivalent circuit of signal path is obtained. Insertion Loss and VSWR curves of relay are obtained through simulation of the equivalent circuit. The extraction methods of parameters proposed in this paper are valuable for the design and analysis of high frequency relay.
