Prof. David Skellern



Leveraging device, circuit and advanced packaging technologies for integrated space communications and awareness


Dr Skellern worked in radioastronomy for 10 years, taught and researched electronics at Sydney and Macquarie Universities for 16 years and, concurrently for seven years, was a Member of Technical Staff and Visiting Academic at HP Labs. He came to prominence in the IT sector through Radiata Inc, which he co-founded in 1997 to build wireless LAN chips based on research he initiated and led at Macquarie University in collaboration with the CSIRO. Radiata developed the world’s first IEEE 802.11a High Speed WiFi chips. Radiata was acquired in 2001 by Cisco Systems, where he was Technology Director of the WLAN Business Unit, which grew to $1B annual revenue using the Radiata team chips. 

Dr Skellern was CEO for six years from 2005 of NICTA, Australia’s ~700-person ICT national research centre (now part of CSIRO’s Data61 Group).

Among other past parallel activities, he was:

  • Chair of the Australian National Committee for Radio Science (1990-1999)
  • Non-Executive Director of the Capital Markets CRC 2004-2019 and Chair 2013-2019; and Chair (2019-2022) of The RoZetta Institute, an independently funded fintech research centre, which absorbed former CMCRC researchers and research students
  • Member (2017) and Chairperson (2018-2022) of the Radioastronomy National Facilities Steering Committee (the ATSC – a Committee of the CSIRO Board)

He is now:

  • Visiting Professor, Imperial College London;
  • Adjunct Professor, Macquarie University;
  • Non-Executive Director (NED) and Chair of the Boards of Quasar Satellite Technologies Pty Ltd; Digicash Pty Ltd; and the NSW Semiconductor Sector Service Bureau JV.
  • NED of Trovio Pte Ltd and METS Ignited Ltd, the Australian Mining Equipment, Technology and Services Growth Centre;

Dr Skellern holds BSc, BE (Hons) and PhD degrees from The University of Sydney, and an Honorary Doctor of Science from Macquarie University.

He has awards for research, innovation and entrepreneurship, including:

  • Officer in the Order of Australia in 2012 for distinguished service to science and engineering as a leading researcher and for design and development of world-leading information technology.
  • The 2017 IEEE Masaru Ibuka Award, jointly with John O’Sullivan and Terry Percival, for pioneering research and development of high speed WiFi.


The Semiconductor Sector Service Bureau (S3B) was initiated by the New South Wales (NSW) Government Office of the Chief Scientist & Engineer and received funding in 2022 as part of a broader effort to enhance the involvement of NSW and Australia in the global semiconductor industry. S3B serves as an advocate for the semiconductor sector, fostering connections among companies, researchers, and local/global semiconductor service providers. These connections encompass training, computer-aided design, intellectual property, prototyping, tooling, packaging, testing, and production.

In its first year of operation, S3B identified numerous opportunities where advanced packaging could have a profound impact, opening up new horizons for semiconductor system design, performance, cost efficiency, and overall effectiveness. In this presentation, we will delve into the realm of advanced semiconductor packaging in the context of a specific project currently underway at Quasar Satellite Technologies (QuasarSat). QuasarSat is in the process of adapting CSIRO’s radioastronomy multi-beam phased-array technology for use in the rapidly expanding field of satellite communications. Achieving this adaptation at X-band and K-band frequencies is only feasible by using custom semiconductor designs.

Over the 20 months leading up to September 2023, the number of operational satellites orbiting Earth experienced a remarkable 38% surge, reaching a total of 6718. This surge can primarily be attributed to technological breakthroughs that have significantly reduced the cost of satellite construction and launch. Projections indicate that the satellite count is poised to increase with an annual compound growth rate approaching 40%, ultimately resulting in an estimated additional 58,000 satellites launched by 2030. This estimation is based on data from “FCC filings since approximately 2016,” as documented in the US Government Accountability Office’s report on Mitigating Environmental and Other Effects of Large Constellations of Satellites.

The most substantial and rapidly expanding portion of this satellite proliferation involves low Earth orbiting (LEO) satellites, positioned at altitudes below 200 kilometres from Earth’s surface. These LEO constellations are central to delivering consumer-level internet services on a global scale. Their operation hinges on a combination of satellite links and ground station internet gateways, serving as a vital bridge between remote users and global internet services. Traditional ground station antennas typically employ single-beam, mechanically steered dishes, enabling communication with one satellite at a time.

QuasarSat’s groundbreaking multibeam phased array ground station design takes on two significant challenges that will become progressively more complex as satellite numbers continue to rise. Firstly, it aims to substantially reduce the cost of ground station communication infrastructure compared to the deployment of traditional ground station antennas. Secondly, it seeks to provide essential space domain awareness to ensure the safe and reliable operation of the satellites in the midst of an increasing presence of numerous satellites and orbital debris.

Against the background of the phased array technology heritage, it is also worth noting that QuasarSat’s system holds the potential to mitigate the effects of satellite radio frequency interference on radioastronomy observations.

Communication at terahertz carrier frequencies is a promising way to satisfy the ever-growing demands for high-speed wireless networks. However, practical feasibility of terahertz communications systems has been limited by the low radiation power of terahertz transmitters and low sensitivity of terahertz receivers. This presentation introduces plasmonic terahertz transceivers, which offer significantly higher terahertz radiation powers and detection sensitivities compared to existing technologies. Thus, they allow potential use of atmospheric transparent bands in the terahertz regime for increasing wireless communication data rates.
