Background and justification:

Achievements and status: 
• Flight heritage: Achieved TRL-8 on the CURIUM-1 mission for the UHF-TX functionality. 
• Commercialization: Outsourced the assembly process. Already delivered an EM and signed multiple contracts for EM & FM 
deliveries in 2025, among which is the HELEO mission, where LSF is part of a larger consortium. University teams constitute the 
majority of our client base.
• Community utilization: A modified version of the board is utilized by a university team on their CubeSat project.

Achievements and status: 

• Both cylinders have been manufactured up to spec and shipped to the end-user. 
• Both cylinders have been accepted by the end-user

Benefits: 

• Tailored lattice design parameters to optimise the design for the defined load cases. 
• Mass savings in comparison to traditional monolithic designs of around 50% (of the composite part, without mounted equipment)

The project included the design, fabrication, and characterization of key components such as transmission lines, resonators, and third-order filters in GGW technology. These components were manufactured using 3D screen printing and then subjected to rigorous testing to validate their electrical and geometric properties. A key technical challenge was to maintain dimensional tolerances within ±15 µm and surface roughness (Ra) below 3 µm to ensure optimal performance at high frequencies.
