SWISSto12 completed the qualification program in January 2024, delivering the three integrated feed chains to Northrop Grumman for payload integration. The space-qualification and shipment of SWISSto12's RF Antenna Feed Chains to Northrop Grumman represents a significant milestone in the availability of next-generation RF payload solutions. SWISSto12's RF Feed Chains are designed as fully-integrated monolithic assemblies; including diplexers, filters, polarizers, horn apertures and mechanical interfaces 3D printed as a single-piece assembly. SWISSto12's proprietary Radio Frequency Additive Manufacturing (RFAM) process allow for design optimization to minimize size and weight, while successfully meeting the stringent RF performance and qualification requirements established for Northrop Grumman's commercial GEOStar-3 program.
