Nujira has opened a new Centre of Excellence for efficient RF transmitter design in cellular and broadcast applications based on its Coolteq modules. The Centre, located near Bath, is led by Simon Whittle, who has more than 25 years experience of base station and high performance transmitter development. He will be supported by a team of specialist engineers offering RF systems, RF power amplifier, DSP and FPGA design skills.
"Improving the efficiency of RF transmission is seen as critical by mobile networks and broadcasters alike, as they seek to manage their operating costs going forward as well as to achieve their Corporate Social Responsibility goals," said Tim Haynes, CEO, Nujira. "Simon Whittle and
his team are available to work with customers on a consultancy basis to address project-specific design challenges. There is a pool of RF systems, digital pre distortion and Digital/Analog IC design expertise in the Bristol area, and our new office harnesses this to help our customers bring to
market the most efficient possible RF transmitter design achievable within their project parameters."
Nujira's CoolTeq power modulator modules are said to halve the power consumption of Class AB RF amplifiers in systems with high peak average ratio signals. The modules use High Accuracy Tracking (HAT), a technology for improving the efficiency of RF power amplifiers.
Simon Whittle joins Nujira from PowerWave Technologies where he was Product Manager for Digital Radios, managing the design and production transfer of high power UMTS and WiMAX digital transceiver products for major OEMs. He was a founding director of Toracomm Ltd, acquired by Powerwave in 2001, which provided RF and signal processing design consultancy services to clients including Nokia, Lucent, TTPCom and IPWireless. Simon has an Honours Degree in Electronic and Electrical Engineering.
