交叉耦合在直线型波导滤波器中的研究

利用相位关系和交叉耦合的模型,提出了直线型波导滤波器的一种关于交叉耦合的具体实现方法:即在不相邻的腔体之间直接用同轴线引入交叉耦合。采用这种方法设计了一种五腔滤波器,应用HFSS软件进行了仿真验证。结果表明,所设计的滤波器整体结构得到简化,中心频率为8.5 GHz,带宽为150 MHz。

Research on linear waveguide filter with cross-coupling

By using two models both the cross-coupling and phase relationshipsc,the realizing method of the linear waveguide filter with the cross-coupling was proposed,which was that the cross-coupling was introduced directly between non-adjacent cavities by using coaxial cable.The five cavities filter was designed by using the method and was simulated by using HFSS.Results show that the whole structure of the filter is simplified,and the center frequency of the filter is 8.5 GHz,the bandwidth is 150 MHz.
