French MMIC foundry specializing in GaN and GaAs chips for 5G base stations, satellite payloads, and millimeter-wave systems.
UMS is a French semiconductor company specializing in the design and manufacture of monolithic microwave integrated circuits (MMICs) based on gallium arsenide (GaAs) and gallium nitride (GaN) technologies. They produce RF and microwave components used in satellite communications, 5G base stations, and defense/space applications. Their work spans the full chain from chip design through advanced packaging (system-in-package, 3D integration) to reliability engineering for high-frequency electronics operating at millimeter-wave frequencies.
5G_GaN2 (coordinated, largest budget) focused on GaN-based RF transceivers for 5G base stations; MyWave addressed millimeter-wave communications; OSIRIS targeted SiC substrates for microwave circuits.
Keywords across 5G_GaN2, MyWave, and OSIRIS consistently reference millimeter-wave, RF CMOS, Ka/E band, and phased array technologies.
5G_GaN2 lists packaging, system-in-package, and 3D integration as key topics; iRel40 addresses chip-package-board reliability.
PAMPA focused on plastic components for next-generation SatCom payload microwave equipment.
iRel40 addresses physics of failure, robustness validation, AI/ML-based prediction, and design-for-reliability in electronic components.
UMS began its H2020 participation (2015-2017) with foundational work on microwave component materials — SiC substrates for power circuits (OSIRIS) and plastic components for satellite payloads (PAMPA). From 2018 onward, the focus shifted decisively toward 5G wireless infrastructure, with GaN-based transceivers for base stations (5G_GaN2) and millimeter-wave antenna systems (MyWave), while also branching into AI-driven reliability engineering (iRel40). The trajectory shows a company moving from component-level material research toward system-level 5G solutions and smart manufacturing quality assurance.
UMS is converging on 5G/6G millimeter-wave hardware with increasing attention to AI-driven reliability, positioning them for next-generation wireless infrastructure projects.
UMS primarily joins consortia as a specialist participant (4 of 5 projects), contributing deep semiconductor expertise to larger teams. They coordinated one major project (5G_GaN2, their largest by far at EUR 1.1M), demonstrating they can lead when the topic aligns with their core GaN competence. With 113 unique partners across 16 countries, they operate as a well-connected specialist rather than a hub — valuable for their specific technical contribution rather than broad project management.
UMS has collaborated with 113 distinct partners across 16 countries, reflecting broad European reach through participation in large ECSEL and RIA consortia. Their network spans both academic institutions (MSCA training network) and industrial partners in the semiconductor and telecom sectors.
UMS is one of Europe's few independent MMIC foundries with proven capability in both GaAs and GaN technologies — a critical strategic asset given Europe's push for semiconductor sovereignty. Their combination of satellite-grade reliability heritage with 5G millimeter-wave design makes them a rare partner who can bridge space and telecom applications. For consortium builders, they bring actual chip fabrication capacity, not just research — making them a credible path from prototype to product.
