The startup company Acconeer has recently received a large investment for further commercialisation of the technology of integrated microwavecircuits. Acconeer was founded in 2011 and uses solutions that have come about as a result of the research being done at EIT by Lars-Erik Wernersson's research group. We sat down to have a chat with him about the research behind the successful enterprise.
The group's most important breakthroughs had to do with the very low power consumption and the possibility of generating extremely short, coherent pulses. “Today we're down to 60 ps and we're doing it in 60 GHz areas where we, thanks to the high frequency, achieve very high accuracy”, Lars-Erik says. Coherence is important in this context as it provides access to useful phase information when the pulses propagate and interfere.
Communication turned into radar
When the research first started it was seen as having the potential for communication technology applications. With time, however, the technology became more and more interesting for use with radar, material characterisations and spectroscopy. If communication is ruled mainly by standardisation, radar technology is a more flexible area of research, guided instead by applications and how we use them. Follow the frequency regulations but otherwise use it freely!
