Eta Devices Launches ETAdvanced - Next Generation Envelope Tracking for Smartphones

ETAdvanced Brings Game-Changing Battery-Life Improvements to Smartphones Including Support for LTE Advanced and CMOS PAs

BARCELONA, SPAIN--(Marketwired - Feb 24, 2014) - Eta Devices, Inc. is launching Eta5, the world's first smartphone power management chip for ETAdvanced at the 2014 Mobile World Congress in Barcelona, Spain from February 24-27.

"ETAdvanced is the future of envelope tracking and we're proud to be the first company to bring this next generation technology to the market," said Mattias Astrom, CEO and founder of Eta Devices. "Everyone is increasingly frustrated by the short battery lives of their smartphones. ETAdvanced extends the battery life by up to 50% by significantly increasing the efficiency of the power amplifier which consumes as much as 70% of the power in a smartphone."

Mobile communications is experiencing explosive data growth and LTE is rapidly becoming the leading technology. At the end of 2013, the global telecom industry trade association, GSMA, recorded 230 LTE network deployments and projected over 1 billion customers on LTE networks by 2017. To meet the demands of increasingly data hungry customers, future LTE deployments will focus on LTE Advanced, the latest version of the LTE standard.

"A challenge with LTE Advanced is that the technology is using ultra wideband channels of up to 100 MHz," said MIT Professor Joel Dawson, CTO and founder of Eta Devices. "No existing efficiency enhancing technology, including envelope tracking, is capable of supporting channels wider than 20-40 MHz. Once LTE Advanced is launched by mobile operators, smartphones without ETAdvanced will suffer from significantly shorter battery life compared to today, and many users may find themselves out of battery by lunchtime. This means users will only really get to enjoy the benefits of LTE Advanced if the technology is coupled with ETAdvanced in smartphones. Otherwise, LTE Advanced will remain a showcase technology at Mobile World Congress but without practical use to consumers."

Beyond increasing the efficiency of conventional GaAs PAs, the additional improvements of ETAdvanced make it possible for CMOS PAs to operate more efficiently than the best GaAs PAs deployed today. Previously the efficiency of CMOS PAs has been too low for inclusion in smartphones.

"Increasing the efficiency of CMOS PAs has been the Holy Grail in the semiconductor industry for a long time. Before ETAdvanced, no technology has been able to deliver the required efficiency levels. This is a truly disruptive innovation that will reshape the industry," said Astrom.

"With its many advantages available already today, ETAdvanced is the only future-proof efficiency enhancing technology on the market," said Astrom. "Envelope tracking was a good first step forward for the industry, but the technology needed to mature into ETAdvanced before real world performance benefits could be delivered."

Eta Devices is a spin-off from the electrical engineering department at the Massachusetts Institute of Technology (MIT). The company's new patented ETAdvanced technology is building on Asymmetric Multilevel Outphasing (AMO) developed at MIT. ETAdvanced is a platform technology with applications for mobile stations, smartphones, tablets and laptop computers.

During the Mobile World Congress in Barcelona, Eta Devices will demonstrate the full power of ETAdvanced for LTE Advanced with transmission over 80MHz channels.
