Chip milestone for Nujira

Cambourne cleantech company Nujira has launched its first commercial envelope tracking chip for mobile handsets.

It has been designed to reduce wasted energy in smartphone power amplifiers by 50 per cent – extending battery life and reducing heat dissipation in smartphones.

“Battery life has always been a key factor for consumers when it comes to mobile handsets, and it is a regular complaint from users of the latest smartphones,” said Nujira chief executive Tim Haynes.

“4G handsets may need to be charged two or three times a day, which will have a catastrophic impact on user adoption.

“The industry consensus is that envelope tracking will become the standard power amplifier architecture for the next generation of handsets because it is the only power optimisation technology which delivers high efficiency over the entire spectrum used for 3G and 4G standards.

“As a result, we see the launch of our first commercial chip for mobile handsets as a significant milestone – not just for Nujira but for the mobile handset sector.”
