Arralis is a leader in advanced millimetre-wave technology.

We operate in the satellite communications, space, and aerospace markets with innovative integrated circuits, packaged modules, sub-systems, and complete high-definition radars and satellite systems. 

Our expertise

Our expertise is in extremely high frequency products up to 110GHz. Our Ka band antennas and transceivers have application in Low Earth Orbit to ground and GEO communications, offering high-rate data throughput. 
We also have Ka band and W band high frequency solutions for intersatellite links. We have developed many products for the European Space agency for scientific missions. Research is also taking place on the use of our products in Space craft landing, debris detection systems and satellite weather monitoring.
