6th CNES/ESA International Workshop on Microwave Filters 

 23rd – 25th March 2015 – Toulouse, France
Co-organised by CNES (Centre National d’Etudes Spatiales) and ESA (European Space Agency)

Filters and multiplexers are key building blocks in science, navigation, earth observation and telecommunication applications.

Satellite systems are in constant evolution to answer to new and changing needs in terms of throughput, coverage, flexibility, RF performances…

For instance, in telecommunication applications, more flexibility in terms of coverage, power and bandwidth allocation is required for future satellite services.

Increase of power level per channel in future broadcast applications demands innovative solutions to cope with challenging thermals and electrical performance at equipment and system level.

In multibeam broadband satellites, where a high number of beams are integrated, there is a significant pressure to reduce size, mass and cost of passive hardware. Additionally, Q/V-band is becoming an important frequency band for future satellite systems.

Navigation applications are requiring increased power with the consequent additional risk due to high power issues.

Science and earth observation applications are mostly related to high/very high frequencies where topologies, manufacturing methods / accuracy and materials play a key role.

All these requirements impact directly the architecture and equipment at payload level including the many types of filters employed.

Improvements of materials, processes and technologies can be enabling for the development of new filter solutions. For instance, in the last years, Additive Manufacturing has generated strong interest for the design and manufacturing of filters for space.

Accurate design tools, for analysis, synthesis and optimisation of filters lead to further improvements.


This 6th co-organised CNES and ESA International Workshop on Microwave Filters addresses the complete development cycle of Microwave Filters, i.e. from filter synthesis to the manufacturing processes.
