Configuration and Customisation

Integration Context

Quality, Compliance, and Supply-Chain Approach

Our Engineering Approach

All RF and microwave subsystems are developed with an integration-first engineering approach, ensuring predictable behaviour at both module and system level. This approach includes:

Defined RF, power, control, and mechanical interfaces to support system integration
Stable RF performance across operating conditions, including temperature and load variations
Robust mechanical construction suitable for fielded and platform-based deployment
Clear, controlled documentation supporting programme, qualification, and lifecycle activities
