Description
In parallel to KABESA project (Ka Band Payload Data Downlink Electronically steerable Antenna), Thales Alenia Space in France was awarded by ESA for the development of a Ka band ferrite phase shifter (ESA Contract No 4000111738).
Indeed, this ferrite phase shifter is the key device which provides the electrical beam scanning functionality while allowing a high efficient solution thanks to the low loss properties of the ferrite technology.
In the frame of this contract, 2 Demonstrators have been developed, based on Exxelia-Temex European ferrite supplier.
The measured performances are comparable to published state of the art and good enough to validate the design of the ferrite phase shifter and respond to KABESA needs.
The presentation will address the following topics :
• Context and objectives of the study
• Recall of the ferrite phase shifter concept
• Design description
• Demonstrator Test plan and Test results
• Recommendations for the development plan of the ferrite phase shifter Flight model
