Mitsubishi Electric, Nokia Bell Labs, UC San Diego Develop World s First Ultra-Fast GaN Envelope-tracking Power Amplifier for Next-Generation Wirele Base Stations

19/05/2017

High-speed operation of envelope-tracking power amplifier will help reduce energy consumption of next-generation wireless base stations

TOKYO, May 19, 2017 - Mitsubishi Electric Corporation, Nokia Bell Labs and the Center for Wireless Communications at UC San Diego announced today their joint development of the worlds 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 state-of-art performance thanks in part to Mitsubishi Electrics 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 worlds widest modulation bandwidth for this purpose as of May 19, 2017.

Key Features

The new GaN envelope-tracking power amplifier uses Mitsubishi Electric high frequency GaN in supply-modulation circuits, which enable high-speed operation. The result is highly efficient amplification of complex signals with modulation bandwidth up to 80MHz, which is four times wider than the signals reportedly used in other envelope-tracking power amplifiers. The technology achieves a world-class drain efficiency of 41.6% in such wide-bandwidth operation, thereby reducing base-station energy consumption while increasing wireless communication speed and capacity.

Further, the real-time DPD system enables pre-distortion for wideband signals to correct the output signal from the power amplifier, resulting in an adjacent channel leakage ratio (ACLR) of -45dBc for LTE 80MHz signals, which satisfies the wireless communication standards.

In view of its leading system-level performance, the new envelope-tracking power amplifier is believed to be a highly promising candidate for next-generation wireless base stations.
