RF hardware hasn’t kept up with New Space
Space, telecom, defense and medical programs all need miniaturized, high-performance RF filters, diplexers and antennas to meet growing demands for compactness, weight reduction and performance.
Bulky, heavy RF hardware
Classical filters and front-ends drive up mass and volume, and every kilogram sent to orbit costs CHF 8,000–15,000.
Power handling limits
Thermal dissipation and the multipactor effect constrain performance in high-power space and defense systems.
Slow, costly production
Existing solutions mean long lead times and high non-recurring engineering costs for every new specification.
Limited adaptability
New Space, 5G/6G and defense programs need hardware that reconfigures without a full redesign.
Two topologies, built for space from day one
A coaxial Stepped-Impedance Resonator (SIR) design covering UHF to X-band, and a Locally Resonant Metamaterial design covering X-band to Q/W-band, both dielectric-free and volumetric, applied across filters, diplexers, antennas, phased arrays and RF front-ends.
Advanced miniaturization
At least −30% mass and volume versus classical filter topologies, at equivalent electrical performance.
Improved power handling
Multipactor immunity and thermal behavior designed in from inception for space constraints (ECSS), not retrofitted.
Fast, modular production
Manufacturing compatible with CNC machining and additive manufacturing, built for New Space and telecom timelines.
Cost optimization
One design and manufacturing process spanning a wide range of specifications, without starting from scratch.
Rooted in EPFL
Rooted in EPFL’s Laboratory of Wave Engineering and Microwave and Antenna Group, UMI Technologies turns award-winning RF research into hardware built for space, telecom, defense and medical applications.
Built for demanding sectors, on and off Earth
The market for RF components, antennas and front-ends across space and telecom is growing fast, driven by New Space and the 5G/6G rollout.
Space
GEO, MEO, LEO and CubeSat payloads: lighter filters and diplexers for tighter mass and volume budgets.
Telecom
5G/6G and SATCOM front-ends that need compact, reconfigurable RF hardware at scale.
Defense
High-power, multipactor-aware components built for demanding radar and communication systems.
Medical
Compact RF equipment such as MRI systems, where footprint and signal integrity both matter.
Aerospace
Avionics and airborne radar/communication systems needing lightweight, vibration-qualified RF hardware.
Trading & finance
Ultra-low-latency microwave links between exchanges, where high-Q, low-loss filters shave microseconds off execution.
Particle accelerators
Narrowband, high-power filters for RF cavities and beamline components under demanding operating conditions.
Nuclear fusion
High-power RF filters and waveguides for plasma heating systems (ICRH/ECRH) in fusion reactors.
