Converters and Local Oscillators for Flexible Payloads

Objectives

The target of the current contract is the study of new flexible converter for flexible payloads and the fabrication and test of a Prototype EM of the whole unit.

 

Challenges

 A Flexible Converter Demonstrator has been designed, manufactured and tested. The test results confirm that:

1) The concept works, one channel within the complete input frequency range can be moved to any channel within the complete output frequency range. 

2) The phase noise cancellation works, the phase noise of the common high frequency LO is cancelled on the output.

Plan

An EM demonstrator and a proof of concept is included and finalized in this Project. Next step will be to refine and improve the LO section and continue the design for LO and RF/IF parts towards an EQM model based on a dialog with potential customers.

Current Status

The Flexible Payload Converter has been designed up to EM level. The Local Oscillator made by Kongsberg Norspace has been delivered to RUAG and integrated into the EM Demonstrator. A test campaign has been performed on the complete demonstrator and a proof of concept has been successfully performed.

After this proof of concept was made a study of an alternative solution for the Local Oscillator was made. This study has given some valuable inputs on how to improve spurious performance on the complete Local Oscillator and has been one step forward in the development of this Concept.

No further activities are planned in this Program.
