High-Power Filter Design in Waveguide Technology: Future Generation of Waveguide Satellite Filters in Payloads Handling Increasing Bit Rates and Numbers of Channels

Abstract

In order 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 the (not only electrical) requirements? It is not always easy to answer

3D-Printed Electromagnetic Band-Gap Band-Pass Filter Based on Empty Single-Ridge Waveguide

“…Waveguide band-pass filters play an important role in current communication systems, because they have a series of advantages in terms of insertion loss and high-power signal handling capability [1]. Normally this type of device is implemented using simple rectangular or cylindrical resonators [2]- [5] and they are usually manufactured using numerical control milling techniques that have a high cost [6].…”

Modelization Methodology for the Quality Factor of Quarter-Wavelength n-Section Coaxial Stepped Impedance Resonators

“…In terms of manufacturing, low sensitivity and low cost are also highly valued. For transmission filters operating at high power, volumic technologies, based, for example, on cylindrical or rectangular resonators are required [1], [2]. Such topologies also offer a very high quality factor, which can be easily calculated using well-known formulas.…”
