Microwave/millimete-wave (mmWaves) filters belong to most common passive components in any microwave/mmWaves network. The number of research contributions devoted to microwave/mmWaves filters is enormous, and even a general overview of all important aspects in filter design and realization is beyond the scope of this presentation. Indeed, we will focus our attention on the use of CAD methods for the designing of selected microwave/mmWaves filters which are typically used on space communications applications (e.g., waveguide technology, cavity technology, interdigital and combline technology, E-Plane technology). Research on microwave filters spans over more than fifty years. The literature related to that topic is very rich, and therefore it is not possible to describe all important steps of this development in a few hours presentation. Therefore, only some but most important milestones in the development of theory and design approaches for microwave/mmwaves filters will be outlined. Subsequently, the projection and designing procedures, accompanied by bred-boarding measurement results, for various space-qualified filters will be presented (e.g., Interdigital and Combline Band-Pass Filters for the Meteosat Second Generation Satellite, a UHF duplexes for the METOP Satellite; a Ku-Band Waveguide-based Band- Pass Filter for VSAT applications; a S-Band Diplexer for multi-beam space qualified Antennas).
