Arralis announces new Ka-band phase shifters

Irish company Arralis, world leaders in building technology and products that are the future of global radar & wireless communications, today announced their new high-frequency analogue phase shifter MMIC products which allow >360 degree analog phase variation with low insertion loss covering two satellite Ka bands, 17-21GHz and 25.5-32.5GHz.

The product is ideal to track fast moving low earth orbit satellites because it is analog and has continuous phase variation, a great advantage over conventional digital phase shifters. The extended frequency range of the upper band chip is also suitable for the proposed 5G band and will be ideal for beam steering base stations. In addition, the added benefit of simplified assembly is possible as these chips are available with an integrated power amplifier.

This development is of great benefit to designers of Connected and Autonomous Vehicle and 5G systems as now a simple, reliable and flat beam steering and continuous tracking antenna can be realised. According to Mike Gleaves, the Arralis Group CTO, “at Space Tech we’ll be showing people our antenna solution, and highlighting how our new MMIC phase-shifters allow the development of high frequency electronically steerable flat antennas. We have in essence developed the technology that allows users to continuously track and communicate with Low-Earth-Orbit (LEO) satellites in a form that can be easily placed within, or on the roof of a vehicle, aircraft, satellite or just about anywhere.”

This release completes the most extensive range of Ka band chips, aimed at the 17-21GHz and 27-31GHz mega-constellation frequency bands on the market. The full range, fabricated on a space qualified process, includes an integrated LO amplifier, IQ mixers and PAs and LNAs. Arralis products will significantly reduce Ka Band transceiver size and are an important enabler in reducing satellite size, power and weight. 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.

The chipset is designed as a one-stop communication solution; from satellite hardware to airborne through to ground.
