Nujira readies power efficiency technology for mobiles

LONDON Power amplifier specialist Nujira has launched its Coolteq-I high accuracy tracking technology IP targeting handset RF front ends for 3G, LTE and WiMAX devices that are likely to hit the market in 2011.
Nujira (Cambridge, England) will be demonstrating the technology at next month's Mobile World Congress in Barcelona, Spain and said an evaluation system is being made available now for about $50,000.
Test chips for Coolteq-I (for low-power) are scheduled for the third quarter of 2009.
Late last year EE Times Europe was given a sneak preview of some of the early test results with the technology and how it extends Nujira's reach from its position of a modules supplier to the cellular infrastructure suppliers to a company selling Intellectual Property for handset suppliers.
Nujira CEO Tim Haynes says the company will be targeting some of the big names that supply PAs and power management devices who may want to integrate the Coolteq-I IP into their devices. He would not say whether the technology would be better integrated into one or the other category.
Coolteq-I is said to halve the cost and double the battery life of a 4G terminal RF frontend compared with existing technologies, as well as covering three to five times the bandwidth of a standard design. Nujira suggests only two PAs would be needed to design a front end covering all 14 bands defined in the 3GPP for LTE, and all of the operating modes, compared with the seven or more devices needed with existing technologies.
The results showed that a handset PA with Nujira's envelope tracking technology is twice as power efficient during HSUPA transmission, and 1.5 times better during W-CDMA transmission compared with the same PA without High Accuracy Tracking.
"This is potentially an industry changing technology," suggests Haynes.
