Europe UK : Nujira announced Coolteq-I, the industry’s most compact and efficient 4G (LTE and WiMAX) handset RF front end, Coolteq-l migrates Nujira’s successful High Accuracy Tracking (HAT™) technology from the base station to the terminal.

Scheduled to showcase at this month’s Mobile World Congress event held in Barcelona, Spain, Coolteq-l enables the creation of an efficient wideband RF front end, covering three to five times the bandwidth of a standard design with up to double the efficiency. Only two PAs (power amplifiers) are needed to design a front end covering all of the fourteen different frequency bands defined by the 3GPP for LTE and all of the operating modes (GSM, EDGE, WCDMA, HSUPA and LTE). This compares to as much as seven or more without Nujira’s solution. Test results show that a handset PA with Coolteq-I technology is twice as efficient during HSUPA transmissions, and 1.5 times as efficient during W-CDMA transmissions compared with the same PA without HAT. For WiMAX, a Coolteq-l based front end can achieve even greater power savings – of up to 4 times.

According to Tim Haynes, CEO of Nujira, “Our announcement today is an industry first in power efficiency and savings – delivering up to a 50% reduction in cost and power consumption, therefore doubling the battery life of a 4G terminal RF front end when compared with technologies in use today.”

“Power efficiency of 4G handsets is a significant hurdle that device manufacturers will need to overcome,” say Kevin Burden, Director of Mobile Device at ABI Research.

Nujira has released an Evaluation System for Coolteq-l which is available now at an entry level price of $50,000, and is releasing a Test Chip in Q3, 2009. The company is in talks with leading suppliers of ICs to the handset market.
