Mitsubishi Electric Corporation, Nokia Bell Labs, UC San Diego Develop World's First Ultra-Fast GaN Envelope-Tracking Power Amplifier for Next-Generation Wireless Base Stations
May 19 17
Mitsubishi Electric Corporation, Nokia Bell Labs and the Center for Wireless Communications at UC San Diego announced their joint development of the world’s first ultra-fast gallium nitride (GaN) envelope-tracking power amplifier, which supports modulation bandwidth up to 80MHz and is expected to reduce energy consumption in next-generation wireless base stations. Technical details will be presented during the IEEE MTT International Microwave Symposium (IMS) 2017, which will be held in Honolulu, Hawaii, USA from June 4 to 9. To help meet the demand for increasing wireless capacity, mobile technologies are shifting to next-generation systems that use complex modulated signals with large peak-to-average power ratio (PAPR) and extra-wide modulation bandwidth. This will require power amplifiers to operate most of the time at backed-off power levels that are well below their saturation levels. Generally, power amplifiers achieve high efficiency near their saturation power levels, but significantly degraded efficiency at backed off levels, as in the case of 4G LTE signals (>6dB PAPR). Envelope-tracking power amplifiers have been studied extensively as a means to enhance power-amplifier efficiency, but so far the supply-modulator circuit has been the bottleneck limiting modulation bandwidth for advanced wireless communications, such as LTE-Advanced. The newly developed ultra-fast GaN envelope-tracking power amplifier achieves performance thanks in part to Mitsubishi Electric’s high-frequency GaN transistor technology and design innovation for the GaN supply-modulator circuit. Using Nokia Bell Labs’ real-time digital pre-distortion (DPD) system, the power amplifier has demonstrated efficient operation even with 80MHz modulated LTE signals, the world’s widest modulation bandwidth for this purpose as of May 19, 2017.
