Nujira’s envelope tracking technology dramatically improves the energy efficiency of cellular network base stations and digital broadcast transmitters by reducing the amount of waste energy dissipated as heat in the RF Power Amplifier circuit, enabling OEMs to develop products which are smaller, lighter, and cooler. Nujira High Accuracy Tracking (HAT™) Modulator technology dynamically controls the power supply to the PA in line with the envelope of the signal, enabling the creation of highly efficient RF Power Amplifiers for applications with high crest factors, such as OFDM and W-CDMA waveforms. Nujira supplies a complete range of Coolteq modulators, development systems, and supporting digital functions such as Digital Pre-Distortion (DPD) and envelope generation.
