Arralis announces €650,000 ESA contract for plug and play Ka band chipset

New product unlocks advanced capacity for mass consumer applications of on the go satellite communications
June 2017
 

Paris Airshow. Irish company Arralis, world leaders in building technology and products that are the future of global radar & wireless communications, today announced a contract with the European Space Agency (ESA) for their new Leonis Ka band chipset, which will enable massive data rate communications speeds for commercial and science missions. This first phase Ka band Transceiver chipset contract is worth €650,000, which is co-funded 75% by awarded under ESA’s ARTES Competitiveness & Growth programme.

This first of its kind Ka band chipset comprises all of the circuits required to build a K band satellite and ground front end that will connect easily with high power amplifiers and antennas. Ka band is considered the next big thing for satellite technology with its smaller antennas and ground terminals, as well as dramatically lowered costs.

Ka band antennas are 400% smaller than their Ku band rivals which opens up the consumer and connected vehicle markets to high data rate and low latency satellite communications.

Companies such as Facebook, Inmarsat and SpaceX have recently announced their plans to use Ka band to provide broadband services around the globe with the initial SpaceX deployment consisting of an unprecedented 4,425 satellites with Ka band payloads.

Speaking from the Paris Airshow, Michael Harverson from ESA said, “Arralis are developing technologies that are in demand by the global space industry and which form the foundations of European Satellite Communications Space programmes now and in the future”.

The Leonis chipset was developed to meet the needs of the growing demand for low cost Ka band satellite equipment that is simple to interface with current digital internet hardware. Applications include 5G communications, airborne high speed Wi-Fi, low earth orbit mega constellation communications, drone constellations and SAT-Drone-Ground data networks, satellite to automotive connectivity, connected vehicles, last mile and remote internet solutions, and IoT and M2M communications.

Speaking at the announcement in Paris, Barry Lunn, CEO of Arralis said, “We are delighted to continue to deliver the world’s leading satellite communication products to ESAthe global industry. This chipset represents ‘new space’ making space technology deliver real benefits back on earth by providing high speed internet for all. ESA have lead the charge on this and, along with our commercial early adopters, will be able to ensure that thethe first to benefits of from our unique technology are reaped by the wider European and Canadian space industry”.

The full transmit and receive band coverage (17-21GHz and 27-31GHz) allows for both ground to space and space to ground applications and employs image cancelling IQ mixers that can be directly interfaced with modulators and demodulators. Both bands have a 21dBm output power amplifier, an ultra-low noise amplifier, up and down converter mixers and a high output VCO to serve as the local oscillator. In addition, this set is available as a core chip, packaged in a QFN format that will allow a complete RF transceiver to be built with just three chips. An evaluation board is also available to enable developers to quickly experiment and prove designs before committing to production. The devices are all fabricated on a low noise, space-qualified gallium arsenide process to ensure a wide temperature range and long term reliability. The chipset is designed as a one-stop communication solution; from satellite hardware to airborne through to ground.
