At Castle Microwave, we have a history of working with RF and Microwave technology. That’s why we’re proud to partner with Swissto12.

Swissto12's Capabilities

Castle Microwave has a legacy of identifying new technologies and bringing the capabilities of innovative suppliers to the UK RF and Microwave market.

With the development of Additive Manufacturing (AM)/3D printing techniques and an increasing number of defence, aerospace and space applications adopting the technology due to the advantages of providing mass reduction over traditional materials whilst retaining structural integrity, with their proprietary technology in developing AM solutions for RF and Microwave applications, we are excited to now present Swissto12 to our customers!

About Swissto12

Based in Renens, Switzerland, Swissto12 provide a unique capability in providing custom AM solutions at RF/Microwave frequencies. The additive manufacturing process developed by SWISSto12 is complex, leveraging unique, patented technology, and starts with an extensive
radio frequency, mechanical and thermal designing phase in order to optimize the performance, weight of monolithic components or subsystems. Once the optimal design has been reached, the actual 3D printing is achieved with Aluminium, INVAR, PEEK or Titanium materials. On completion of printing, the parts undergo a chemical surface treatment and plating aimed at improving surface roughness and skin conductivity. Finally, all parts are tested and integrated to ensure functionality and comply with both functional and technical requirements.

Parts Swissto12 have printed include waveguide and waveguide components, antenna components (filters, diplexers, slotted waveguide arrays), electronically steered antenna arrays for LEO applications at Ku and Ka-bands and also GEO applications from X to Q-bands, phase matched horn antenna arrays and spiral antennas for EW (ELINT/SIGINT), to name a few examples

 Swissto12 have product deployed on 50 airborne platforms, 32 Naval systems, 16 offshore systems and 16 ‘on the move’ systems, with over 1000+ products in space.

Offering the ability to design and manufacture parts that cannot be produced by machine methods, Swissto12 are the leaders in delivering AM solutions for high-reliability applications. Fill out our contact form or get in touch at to learn more.
