Nujira will be demonstrating its latest broadband PA reference designs for cellular handsets and base stations, delivering 3G/4G amplifier efficiencies of more than 50 percent, at the IEEE MTT 2010 International Microwave Symposium, Anaheim, CA, May 23-28, 2010.

Commenting, Tim Haynes, CEO of Nujira, said, "Operators are demanding lower operating costs and reduced carbon footprint from their next generation infrastructure. Users are demanding higher data rates and longer battery life from 4G terminals and USB dongles. As the only broadband high efficiency PA technology that can fully meet both of these demands, Coolteq is attracting growing interest from all sectors of the industry."

Nujira's Coolteq.L for handsets is inherently broadband, enabling the creation of a 4G/LTE RF front end that covers three to five times the bandwidth of a standard design with up to double the efficiency. Only two power amplifiers are required to cover the 23 frequency bands defined in the 3GPP for LTE and all of the operating modes compared with seven or more without Nujira's solution. This cuts the Bill of Materials cost for the handset RF front end by up to 50 percent.

The increase in efficiency radically reduces the peak and average current consumption of the handset PA, which is fast becoming the major design challenge for HSUPA and LTE handsets and USB modems. Coolteq.L was shortlisted for the 2010 EE Times ACE awards in the Most Promising New Technology category.

The Nujira Coolteq.h power modulator modules for infrastructure products support the development of efficient PA platforms covering the entire 700 MHz to 2.1 GHz spectrum using just three broadband PA platforms, simplifying product development and enabling OEMs to address the growing portfolio management crisis caused by an increasing number of different frequency bands. Nujira will be showing solutions for high power LTE Remote Radio Heads, where the reduction in size, weight and power consumption are enabling a new generation of compact, high efficiency base stations.

Nujira will be exhibiting in Booth 411, and running live demonstrations to selected customers and partners in a private demo suite.
