EnSilica to Develop Next-Generation Ka Band Satellite Transceivers for the European Space Agency

Millimetre wave CMOS chip to form key component in ARTES / CASSIS project and provide next generation automotive communications

30th January 2020, Wokingham, UK  –  EnSilica, a leading provider of custom ASIC design and supply services has announced it is developing a single-chip Ka band transceiver IC for the European Space Agency.  The mmWave IC will form a key component of next-generation, low-cost hybrid automotive communication terminals – enabling vehicles to always be connected.

The IC is being developed as part of ESA’s Advanced Research in Telecommunications Systems (ARTES) project and the CASSIS project (Connected Automotive Satellite Service Integrated System), which is led by the UK Satellite Applications Catapult (UKSAC).

It is estimated that over a quarter (27%) of automotive use cases will require satellite connectivity by 2025, and ubiquitous, high speed connectivity will not be possible through the 4G/5G cellular network alone (source CASSIS).

Operating at up to 31.5 GHz, the custom Ka band CMOS ASIC will form part of an affordable, consumer-scale communications module supporting a flat panel electronically steerable phased array antenna. The hybrid module will communicate with geostationary and low earth orbit (LEO) satellites, 4G/5G infrastructure and Wi-Fi communications to deliver high capacity connectivity to cars, small vessels and aircraft.

Ian Lankshear, CEO at EnSilica said: “Ka band technologies are set to play an increasingly critical role in enabling the next-generation of low-cost satellite and 5G communications systems. EnSilica’s mmWave team’s expertise, coupled with the company’s automotive ASIC supply strategy, ideally position us to help our customers develop such ICs in CMOS and address this growing need.”

Paul Febvre, Chief Technology Officer at the Satellite Applications Catapult said: “We are really excited that Ensilica have joined us to accelerate the development of a new class of satellite terminals to provide low-cost high-performance connectivity for the automotive sector. Ensilica bring the capability and expertise necessary to integrate with automotive systems and then scale-up the manufacturing to deliver products at the right price.”

First samples of the ASIC will be available for evaluation in Q2 2020.

By 2025 it is expected that 27% of automotive use cases will require satellite connectivity since ubiquitous, high speed connectivity for mobile users cannot be delivered by 4G/5G alone. Satellite communications provides unique and complementary features compared to the enormous investments required in terrestrial infrastructure to deliver adequate coverage and capacity to everyone everywhere. The CASSIS (Connect Automotive Satellite Served Integrated System) program, is part of a multi-million-pound UK research and development initiative that aims to put the UK connected vehicle supply chain at the forefront of satellite communications technology and tap into the $160 billion market for mobile satellite terminals and payload technologies.
