France 2030 collaborative innovation program
CAPTIVANT2
Advanced RF technologies for energy-efficient 5G evolution, future 6G systems and space connectivity — strengthening European technological sovereignty across critical parts of the radio-frequency chain.
Collaborative R&D program
Targeted reduction in energy consumption for relevant amplification and mixed-signal chain functions
Terrestrial and non-terrestrial connectivity
GaN and GaAs technologies among the enabling platforms
The project
From advanced devices to more efficient RF systems
CAPTIVANT2 combines semiconductor technology, RF component development, antenna and system research, and continuous techno-economic analysis to address the next generation of communications infrastructure.
The program addresses critical components of the RF link for advanced communications systems. Its scope spans terrestrial networks and space applications, with particular emphasis on energy efficiency, open European access to strategic technologies and components, and the transition from today’s 5G deployments toward future 6G architectures.
CAPTIVANT2 is coordinated by United Monolithic Semiconductors (UMS) and brings together industrial and academic expertise in compound semiconductors, integrated circuits, advanced materials, RF systems, antennas and research.
