Cambridge, UK-based Nujira, an innovator focused on producing energy efficient equipment for the telecoms industry, has raised $12m with Zurich-based SAM joining as a new investor.
Formed in 2002, its envelope tracking technology powers energy efficient 4G cellular terminals, base stations and digital broadcast transmitters.
Keimpe Keuning, investment director at SAM Private Equity, said the firm was committing to Nujira at the pivotal time in the market adoption of envelope tracking (ET).
'With all major smartphone vendors poised to adopt ET in the next few years, Nujira's world-leading technology and dominant patent position marks them out as the key player in this segment,' he said.
Nujira is currently engaged with 16 major smartphone chipset suppliers to embed its ET technology into their reference platforms and expects its Coolteq.L technology to be designed into 4G smartphones in 2013.
Nujira CEO Tim Haynes said, 'ET is fast becoming a mandatory requirement for smartphones, driven by the poor battery life of existing 4G handsets, and the need to support multiple LTE frequency bands for global adoption.
'We have been at the forefront of this technological shift, pioneering the development of ET over the last ten years. This latest investment not only allows us to continue that development work, but also reinforces the growing value of our extensive ET patent portfolio.'
