An overview of all-metal waveguide filters for satellite payloads is offered in this talk. Initially, an historical evolution of this filtering technology, including typical electrical and mechanical requirements, is outlined. Next, recent advancements in full-wave analysis methods and automated design procedures of these filters are reviewed. Then, a Computer-Aided Design (CAD) tool based on such techniques (i.e. FEST3D "Full-Wave Electromagnetic Software Tool for 3D Waveguide Components") is introduced, and its practical application to the analysis and design of several examples of satellite filters is presented. In particular, direct-coupled rectangular waveguide filters, E-plane waveguide technology, dual-mode filtering prototypes and evanescent mode waveguide filters are considered. Classical topologies, as well as more novel configurations for each filter class, are discussed.
