Nujira and Sumitomo Electric Industries Collaborate to bring High Efficiency Power Amplifiers to 3G and 4G Cellular Infrastructure Market

12 February 2008

12 February, 2008 – Cambridge, United Kingdom – Nujira, the company leading the development of energy efficient, high efficiency power amplifier technology for next generation wireless networks, and Sumitomo Electric Industries (SEI), today announced they are collaborating to bring high power, high-efficiency WiMAX and LTE (Long Term Evolution) RF Power Amplifiers to the cellular infrastructure market.

Tim Haynes, CEO of Nujira, said: "Working with a strategic partner such as Sumitomo is very important to Nujira, especially given their strong market presence in Japan, the first country in the world to deploy LTE commercially. Nujira’s technology enables infrastructure vendors to reduce the power consumption and size of base stations, reducing both network rollout costs and ongoing energy costs – an increasingly important consideration for operators worldwide."

Yoshikazu Nishiwaki, General Manager of Broadband Equipment Development Department at SEI commented: "SEI is working with Nujira to lead the way in high efficiency amplifier design. By using Nujira’s HAT™ technology, SEI will offer customers industry leading RF Power Amplifier efficiencies that significantly reduce operating carbon footprint. This collaboration further demonstrates SEI’s continued commitment to our customers and the environment."

"Current power amplifier designs for WCDMA, WiMAX and LTE are very inefficient," said Julian Hildersley, VP of Strategy and Marketing at Nujira. "Nujira’s High Accuracy Tracking (HAT™) modulator technology, allows power amplifier designers to dramatically improve power amplifier efficiency. Nujira’s technology dynamically controls the power supplied to the amplifier ensuring that very little is wasted as heat – an essential requirement for next-generation technologies".

Under the terms of their agreement, SEI will develop and market high power RF amplifiers targeted at next generation cellular base stations using Nujira’s HAT™ module.
