摘要

给出了k波段滤波器和双工器的设计方法和实现实例。在设计过程中,将三维电磁仿真与电路仿真相结合。考虑到谐振器圆角等CNC加工过程产生的所有影响,3D模拟产生准确的结果。首先在三维时域有限差分模拟器中对滤波器和其他元件分别进行了分析和优化,然后在电路模拟器中对元件之间的距离进行了优化,得到了双工器的完整特性。

Design and realization of low cost waveguide filters and diplexers
The design method as well as realization examples of the K-band filters and diplexers are presented. In the design process the 3D electromagnetic simulations and circuit simulations are combined. The 3D simulations produce accurate results taking into account all effects resulting from CNC fabrication process like rounded corners of resonators. First the filters and other elements are analyzed and optimized separately in the 3D FDTD simulator then the complete characteristics of diplexers are obtained in the circuit simulator where the distances between the elements are optimized.
