Envelope Tracking technology firm Nujira has launched an IC in its Coolteq.L product family of Envelope Tracking (ET) power supply modulators for mobile handsets.
Nujira’s NCT-L1100 is designed to deliver a chip that reduces wasted energy from power amplifiers (PAs) in mobile handsets by more than 50%, cutting heat dissipation and extending battery life.
The new chip demonstrates power conversion efficiencies in excess of 80% and supports the maximum 20MHz channel bandwidth of LTE and is compatible with multiple air interface standards, including TDD and FDD LTE.
The new Coolteq.L chip features the OpenET analogue envelope interface and a MIPI RFFE control interface.
Nujira will provide platform chipset vendors with evaluation boards and engineering support for integration into reference designs for smartphones and data devices.
Nujira CEO Tim Haynes said the industry consensus is that Envelope Tracking will become the standard PA 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," said Haynes.
