The number of channels and the power per channel in satellite payloads is continuously increasing. Therefore there is a strong need for high power, low loss output multiplexers with as small a footprint as ever possible.
The objective of the project therefore is the development and qualification of a new type of output multiplexer with:
- Improved power handling capability (300 W per channel),
- Reduced insertion loss,
- Improved removal of heat from the filters,
- Dramatically reduced footprint area,
- Reduced mass.
Key issues are:
- Advancement of design software,
- Electrical optimisation,
- Mechanical and thermal design.
Expected benefits brought by the project are:
- Improved electrical performances,
- Reduced mass,
- Reduced footprint,
- Improved reliability by reduced number of parts.
Output multiplexers constitute a basic element in the payload of a telecommunication satellite. They connect a multitude of power amplifiers to the transmit antenna.
The project has 4 main phases:
- Design trade-offs,
- EQM development and manufacturing,
- Qualification testing.
EQM qualification (5 and 10 channel OMUXes) completed. Final Review successfuly performed.
