Nujira and TTP Demonstrate RF Power Amplifier

Nujira has successfully demonstrated its ultra-high efficiency RF Power Amplifier (PA) operation with DVB OFDM signals, supported by TTP and the Carbon Trust (News - Alert).

 

Tim Haynes, CEO of Nujira, said this demonstration shows that the power efficiency savings that the company has demonstrated with WCDMA and WiMAX can be achieved with even greater effect for OFDM-based mobile and digital TV standards at UHF, such as DVB-T, DVB-H, ISDB-T, and MediaFLO.

 

Antony Rix, senior consultant at TTP explained that the broadcast and cellular industries are major electricity users, which results in high operational costs and CO₂ emissions. He noted that this highly successful demonstration shows Nujira’s HAT envelope-tracking technology has the potential to cut the electricity consumption of broadcast transmitters by up to 50 percent.

 

According to Nujira, the demonstration was performed using the latest release of Nujira’s High Accuracy Tracking Development System, combined with a bespoke RF platform jointly developed by Nujira and TTP that allows a direct comparison between PAs operating at 2.1GHz and UHF. The transmissions reportedly met broadcasters’ requirements for modulation error ratio and adjacent channel protection. This development, and the related modeling and market research, was supported by the Carbon Trust – TTP Incubator, funded by the Carbon Trust.

 

Business Incubator Manager at the Carbon Trust, Rachael Nutter noted this collaboration is an excellent example of the Carbon Trust’s charter to work with industry to develop low carbon technology and support its commercialization. It has already received interest from network operators and equipment suppliers who have been impressed by the power reductions achieved.

 

Haynes further explained that several new transmitters will be required due to the planned Digital Switchover taking place in the EU and elsewhere around the world. This demand provides the broadcasting industry with a tremendous opportunity to reduce its energy usage, operating cost, and carbon footprint by adopting transmitters equipped with high-efficiency PAs.

 

He believes that Nujira’s technology is uniquely suitable for broadband OFDM transmitters and adds that their company looks forward to playing its role in improving broadcasters’ profitability and their environmental credentials.

 

Nujira is a supplier of energy efficient, ultra-high efficiency RF power amplifier technology for next generation wireless networks.
