We are building the future of radar, wireless communications and geo-location…

Arralis is a rapidly scaling technology company, providing world leading expertise in RF, micro and millimetre-wave technology. Our head office is in Limerick, Ireland, with design offices in Belfast and Manchester, our business development and sales team is based in Harwell in the UK.

Arralis excels in Monolithic Microwave Integrated Circuits (MMICs), packaged component modules, proprietary antenna technology and integrated radar and communications front-end platforms.

Our core focus includes E and W bands where we can take advantage of their highly desirable attenuation windows, allowing the development of very high resolution radar and antennas; applications of which include autonomous vehicles, satellite communications, helicopter landing, space science and military defence. We also focus on the emerging K/Ka band satellite communication frequency giving very high data rates from satellite to ground and inter satellite links.

Arralis products, which are the ultimate in precision and innovation, are used in both terrestrial and space environments where accuracy and reliability are critical. Arralis works with some of the world’s largest aerospace, automotive, defence and communications companies.
