Arralis: Strategic Enabler of European Radar and Satellite Autonomy

Arralis is a European technology company pioneering advanced millimeter-wave radar and satellite communication systems. Its expertise in high-frequency RF microelectronics has propelled it to the forefront of next-generation aerospace and defense innovation[1][2]. Born from research roots in Ireland and Northern Ireland, Arralis develops miniature Monolithic Microwave Integrated Circuit (MMIC) chips, antennas, and integrated sensor platforms operating at Ka, E, and especially W-band frequencies (up to 94–110 GHz)[3][4]. These ultra-high frequency technologies, once confined to costly military programs, are being made more accessible through Arralis’s engineering breakthroughs. From all-weather helicopter landing radars to flat-panel satellite antennas, the company’s products deliver unprecedented resolution and data rates in compact form factors[5][6]. Such capabilities address critical needs for Europe’s strategic autonomy: enabling military operations in degraded visibility, secure high-bandwidth communications for space and defense, and advanced sensor networks for multi-domain awareness. Arralis’s trajectory – including early contracts with ESA, the UK Ministry of Defence and even Chinese aerospace firms[7] – reflects both the promise and the geopolitical sensitivities of its cutting-edge technology. Now reestablished under allied ownership and branding, the company stands as a noteworthy European innovator in dual-use high-frequency systems, intriguing defense planners and industry leaders alike.
