In this paper, a modular waveguide filter platform suitable for educational and prototyping purposes is presented. The waveguide filter platform is dimensioned to work in the F-band (4.9–7.05 GHz). The design of the platform is discussed and versatile application possibilities are shown in many examples. The platform can be used to realize generalized Chebyshev filters with or without cross-couplings by exploiting TE101 and TE102 mode cavities. Transmission zeros can be introduced by the utilization of wires or aperture couplings. Filter topologies based on the extracted pole technique can be examined as well. Small changes in the set-up also allow the realization of a gap waveguide filter, a diplexer set-up as well as filters with frequency-dependent coupling apertures. Most required components can either be purchased cheaply or be manufactured with a three-dimensional printer.

在本文中，提出了一种适用于教育和原型设计目的的模块化波导滤波器平台。波导滤波器平台的尺寸设计为在 F 波段 (4.9–7.05 GHz) 中工作。讨论了平台的设计，并在许多示例中展示了多种应用可能性。该平台可用于通过利用TE 101和TE 102实现具有或不具有交叉耦合的广义切比雪夫滤波器模腔。可以通过使用导线或孔径耦合来引入传输零点。也可以检查基于提取极点技术的滤波器拓扑。设置的微小变化还允许实现间隙波导滤波器、双工器设置以及具有频率相关耦合孔径的滤波器。大多数需要的组件既可以廉价购买，也可以使用 3D 打印机制造。
