Objectives
The goal of the project was the development and qualification of an innovative high-power Ku-band feed chain at EQM level.
- Significantly higher multipacting threshold,
- Combined Tx/Rx operation with reduced PIM risk,
- Improved thermal performance,
- Increase of the operational frequency band width,
- Excellent RF performance.
The feed chain shall keep the modular interface philosophy to allow for individual adaptation to specific customer requirements.
Challenges
- Generic Design covering future requirements,
- Highly reproducible,
- Integrated manufacturing technology (minimising the number of RF interfaces, based on a monolithic manufacturing process for OMT),
- Increased multipaction and PIM performance,
- Excellent RF performance.
Plan
Development and qualification of an EQM High-Power Antenna Feed System covering the full operational Ku Band (FSS) with high interface flexibility (el. & mech.) for implementation into a dedicated antenna as complete feed chain or at component level.
Current Status
Project finalized with the successfully verification and qualification of the Engineering Qualification Model (EQM) of the High-Power Feed Chain.
