Nujira Ltd has developed market-leading power amplifier technology that solves key environmental and power efficiency problems faced by the wireless industry. Power amplifiers, found in every cell phone and cellular base station, are critical to the transmission of all wireless signals.

WCDMA, WiMAX and DVBH technologies have heralded a new era of high spectrum efficiency communications but at the cost of low efficiency power amplifiers. The consequent increase in power consumption and heat is proving to be one of the most significant problems facing the wireless industry today both financially and environmentally. Nujira’s high power High Accuracy Tracking (HAT) Modulators enable infrastructure and handset OEMs to avoid this reduction in amplifier efficiency.

Amadeus led the seed investment round in Cambridge-based Nujira and has participated in all subsequent rounds. Andrea Traversone is a non-executive director on the Board.
