摘要
介绍了一种微波低通滤波器的简便设计,从典型的巴特沃斯型(最平坦型)低通原型滤波器的频率特性分析给出低通滤波器的设计方法。为了达到微波滤波器的设计,采用Richard变换,将集总元件变换到传输线;同时采用Kuroda恒等式,以利用传输线段来分隔滤波器元件。通过实例来说明这种设计方法的简便、快捷,并用MATLAB软件仿真。
A simple design for microwave low pass filter is described,then a design method is given based on analysis of the frequency characteristic from the typical Butterworth low pass filter （the smoothest type）.In order to accomplish the filter design,Richard transformation is adopted,thus to transform the lump part into the transmission line,while the Kuroda formula is used in order to separate the filter element with the transmission line.The experiment indicates that this design is simple and easy,and verified by simulation with MATLAB software.
