Nujira achieves record 40MHz bandwidth for 4G LTE-Advanced signals

The bandwidth performance landmark was made using the company's NCT-L1300 - the latest in its Coolteq.L range of power supply modulator chips - and a commercially available rf power amplifier. The results used the Carrier Aggregation feature of the LTE-Advanced specification to transmit a 200 Resource Block LTE waveform – the highest bandwidth currently specified, corresponding to an instantaneous data rate of approximately 150Mb/s. Performance was measured at 27dBm at the PA output, corresponding to 23dBm at the antenna, the maximum power permitted for LTE terminals. Nujira's ceo Tim Haynes (pictured), said: "By supporting the highest possible channel bandwidths in ET mode, our Coolteq.L chips offer twice the energy saving of lower bandwidth ET solutions, increasing battery life, improving coverage, and boosting data rates."
