GaN RF power semiconductor devices gained meaningful market share over the last two years, despite a lackluster 2016, with 2017 promising further growth. ABI Research forecasts GaN RF power devices will capture nearly 25 percent of all high power semiconductors for mobile wireless infrastructure in 2017.
While all of the talk of MWC 2017 was about 5G and IoT, for Microwave Journal it was the unprecedented level of integration at the device level that was the most interesting.
MaxLinear announced a baseband system on chip (SoC) for broadband wireless transmission systems. The MxL85110 is a full duplex, single carrier, FDD modem that provides a comprehensive processing chain from the various user IP interfaces to the analog baseband signals, including analog-to-digital and digital-to-analog converters.
Qorvo announced two dual-channel switch-LNA modules for base stations, covering 2.3 to 2.7 GHz and 1.8 to 4.2 GHz, respectively. Designed for TDD massive MIMO architectures, each channel integrates a T/R switch to connect the antenna to a two-stage LNA in receive mode or, in transmit, passes the signal from the PA to the antenna.
TowerJazz and The University of California, San Diego (UCSD) demonstrated >12 Gbps from a 5G phased-array chipset operating from 28 to 31 GHz. The chipset was fabricated with the TowerJazz H3 SiGe BiCMOS process.
At the 2017 Mobile World Congress in Barcelona, Qorvo's mobile products business announced two new RF front-end modules for mid-tier phones, four design wins in a "gigabit" smartphone and "the industry's first" 5G RF front-end.
Keysight Technologies Inc. and Samsung Electronics Corp. announced a technology collaboration on 5G development and testing. Keysight and Samsung have entered into a technology collaboration to enable design and deployment of 5G devices to support early operator trials. The initial focus of the partnership is on 5GTF specifications (www.5gtf.org). Future collaboration will include work being done in 3GPP NR.
22 mobile communications companies announced collective support for accelerating the 5G new radio (NR) standardization schedule to enable large-scale trials and deployments as early as 2019. The firms are supporting a proposal to be discussed at the next 3GPP RAN plenary meeting, scheduled for March 6-9 in Dubrovnik, Croatia.
The quest for highly efficient 5G wireless connectivity has been given a boost thanks to a collaboration between a team of 5G engineers from the Universities of Bristol and Lund, National Instruments (NI), and BT Labs, one of the world’s leading providers of communications services. The research team has undertaken field trials of a massive MIMO system at the BT Labs in Adastral Park, Suffolk. The trials were conducted in a large indoor hall mimicking a stadium environment and outdoors within the Adastral Park campus.
