Mitsubishi Electric and Nokia Bell Labs develop GaN amplifier

Mitsubishi Electric, Nokia Bell Labs and the Center for Wireless Communications at UC San Diego have announced the joint development of what is claimed as the first ultra-fast gallium nitride (GaN) envelope-tracking power amplifier, offering support for modulation bandwidth up to 80 MHz and designed to reduce power consumption in next-generation wireless base stations.

To companies explained that to address demand for greater wireless capacity, mobile technologies are adopting systems that use complex modulated signals with high peak-to-average power ratio (PAPR) and extra-wide modulation bandwidth. This requires power amplifiers to often operate at backed-off power levels below their saturation levels, while power amplifiers are typically efficient near to their saturation power level and not at backed off levels, as with 4G LTE signals (>6 dB PAPR).

As a result, envelope-tracking power amplifiers have been evaluated as a means to enhance power-amplifier efficiency, although to date the supply-modulator circuit has proved a bottleneck limiting modulation bandwidth for advanced wireless communications, such as LTE-Advanced.

The newly-developed ultra-fast GaN envelope-tracking power amplifier delivers high performance leveraging Mitsubishi Electric's high-frequency GaN transistor technology and its design for the GaN supply-modulator circuit. Utilising Nokia Bell Labs' real-time digital pre-distortion (DPD) system, the power amplifier has demonstrated efficient operation, including with 80 MHz modulated LTE signals.

The partners claim that this represents the widest modulation bandwidth achieved for this application to date, and is around four times higher than signals used in other envelope-tracking power amplifiers. In addition, the technology delivers a drain efficiency of 41.6% in this wide-bandwidth operation, helping to reduce base-station energy consumption as well as increase wireless communication speed and capacity.

Additionally, the Nokia Bell Labs' 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 -45 dBc for LTE 80 MHz signals, which is compatible with wireless communication standards.

Specifications of the GaN envelope-tracking power amplifier include: support for carrier frequency of 0.9 to 2.15 GHz; output power of 30.0-30.7 dBm; drain efficiency of 36.5-41.6%; ACLR of -45 dBc; and modulation signal of 80 MHz LTE Advanced with 6.5 dB PAPR.

The University of California, San Diego, is a leading university for mixed-signal, microwave and mmWave RFICs, digital communications, applied electromagnetics, RF MEMS and nano-electronics research and hosts the Center for Wireless Communications (CWC), is a university-industry partnership that includes Mitsubishi Electric and Nokia.

Huawei notes call for industry convergence to support next generation PON

Huawei announced that during the first PON industry development workshop held recently in Beijing, a consensus was reached to propose a PON industry development forum to the Broadband Forum (BBF) to support coordination and collaboration among PON standards development organisations including ITU-T/FSAN, IEEE and BBF and thereby enhance industry convergence.

Huawei noted that due to the cost sensitivity of the PON industry, which primarily addresses home broadband access, it was proposed during the workshop that the deployment of next generation PON systems enabling 10 Gbit/s and higher bandwidth will need to take into consideration the external ecosystem spanning transport, Ethernet and data centre networks, Additionally, next generation PON will need to reuse the cost-effective optical/electrical components and technologies deployed commercially at scale.

In addition, it was proposed that to help expand the PON ecosystem, the community should take measures relating to areas such as PON industry development coordination, standard requirement and roadmap management and standardisation coordination and cooperation. Finally, the workshop participants agreed to host future workshops as necessary to enable discussion regarding key technical issues in PON industry development.

Huawei noted that PON is currently the mainstream access technology used by operators for FTTH ultra-broadband deployments. To date, two competing standards have been adopted, the IEEE's EPON/10 Gbit/s EPON and ITU-T GPON/XG(S)-PON, leading to duplication in types of system and related equipment installed in operators' networks, resulting in higher network construction and maintenance costs.

In order to promote a converged PON ecosystem, a group of standards development organisations (SDO) has jointly issued a statement on PON convergence, To help expand PON market scale, share industry chain resources and reduce deployment costs and time to market (TTM), and thereby create a sustainable PON ecosystem, the operator and vendor representatives at the workshop called for the convergence of standards for next generation PON.


The recent workshop in Beijing was attended by representatives from standard organisations such as the Broadband Forum (BBF) and Institute of Communication Standards Research (ICSR), operators including China Telecom, China Mobile and China Unicom, and system and optical module vendors including Huawei, Nokia Shanghai Bell, Accelink, FiberHome, Hisense, Source Photonics and ZTE.
