      Swissto12 has delivered three RF Antenna Feed Chains to Northrop Grumman for a GEOStar-3 satellite, after completing a qualification program. Swissto12 announced the milestone on May 13. 

      GEOStar-3 is Northrop Grumman’s Geostationary (GEO) satellite bus, the bus used in C-band replacement satellites for Intelsat and SES and the Mission Extension Vehcile (MEV) servicing spacecraft. 

      Swissto12 developed, qualified the RF Antenna Feed Chains in various bands for the payload of a commercial GEOStar-3 satellite. This Swissto12’s first delivery to Northrop Grumman for this product. The company 3D prints the product as a single-piece assembly, using a proprietary RF additive manufacturing process.

      “Our novel Radio Frequency Additive Manufacturing coupled with advanced monolithic designs enabled by 3D printing has created a new benchmark in Antenna Feed Chain size, weight and performance,” commented Scott Wolf, managing director of St12 RF Solutions, the U.S. entity of Swissto12.
