High-power filter design in waveguide technology: future generation of waveguide satellite filters in payloads handling increasing bit rates and numbers of channels

To design a filter for a particular application, many issues must first be considered. Which technology will be the most convenient? What design technique will provide better results for a particular set of frequency specifications? Once the device has been designed, will it fulfill all of the (not only electrical) requirements? It is not always easy to answer such questions in advance. In this article, we try to shed some light on these questions when our aim is the design of filters for high-power operation.This article covers work supported by the Spanish Ministerio de Ciencia, Innovación y Universidades–Agencia Estatal de Investigación under Project TEC2017-85529-C3-2-R (AEI, FEDER-EU)
