The new funding round included a new investor, Zurich-based SAM Private Equity, as well as existing investors Amadeus Capital Partners, Climate Change Capital, Environmental Technologies Fund, NES Partners and angel investors.
Commenting, Nujira CEO Tim Haynes said: “As the world leader in Envelope Tracking technology, Nujira remains in an extremely strong market position, and we continue to lead the way both commercially and technologically. 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 10 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."
Nujira announced the first commercial IC in its Coolteq.L product family of ET power supply modulators for mobile handsets in February 2012 at Mobile World Congress. The NCT-L1100 reduces wasted energy from power amplifiers (PAs) in mobile handsets by more than 50%, cutting heat dissipation and extending battery life. In April Nujira also announced the filing of its 150th patent relating to ET, emphasizing its dominant position in the ET intellectual property landscape.
Nujira’s patents cover not only the core technical breakthroughs that underpin Nujira’s high bandwidth, high efficiency Coolteq® ET modulator ICs, but also wider system elements. These include system architectures, timing alignment, linearization with or without Digital Pre Distortion (DPD), PA performance enhancement, system optimization, test & measurement, and production-line calibration techniques.
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’s latest investor, Zurich-based SAM, is a global investment boutique focused exclusively on sustainability investing. The firm’s offering comprises asset management, indexes and clean tech
