Eta Devices Inc. has unleashed what it flaunts as the world's most efficient power amplifier for mobile base stations. According to the company, the device uses patented technology that exploits the extreme performance capabilities of GaN switching power amplifiers, advanced supply modulation and digital predistortion algorithms.

"Our power amplifier architecture brings real sustainability to the world's mobile operators," said Mattias Åström, Eta Devices' co-founder and CEO. "We deliver 70 per cent drain efficiency for 4G LTE, an industry first. By deploying our solution, base station efficiency is doubled compared to current state-of-the-art technology, which saves a tremendous amount of power."

"Until today, mobile operators have not been able to build genuinely sustainable mobile networks," said Joel Dawson, MIT professor and Eta Devices co-founder and chief technology officer. "They have had no choice other than to focus on relatively minor sustainability initiatives such as changing the vehicle fleet to improve fuel economy, office recycling and substituting some flights with video conferences. While commendable, these initiatives have not touched on the operators' core business of running mobile networks and as a result the impact has been relatively minor. But, there's a new game in town. Operators can now double the efficiency of their mobile networks and realise substantial reductions in power usage, resulting in a major reduction in greenhouse gas emissions, and at the same time huge cost savings from using less power."
