The IEEE Microwave Theory and Techniques Society, other IEEE Societies, and additional IEEE resources offer a wealth of information on 5G communications (and its alter ego, the Internet of Things). In addition to more than 3,200 technical papers indexed under “5G mobile communications” on IEEEXplore, the trove includes webinars and videos aimed at bringing members up to speed. Here are some of the relevant offerings…beginning, of course, with the MTT-S’s own webinar series, now just over a year old.

MICROWAVE AND MILLIMETER WAVE POWER AMPLIFIERS: TECHNOLOGY, APPLICATIONS, AND FUTURE TRENDS (2/9/2016)
James Komiak, IEEE Fellow and past MTT-S Distinguished Microwave Lecturer.

This presentation covers Si LDMOS, PHEMT, InP HEMT/MHEMT and GaN HEMT. Content includes principles of operation, structures, characteristics, classes of operation, and state-of-the-art device benchmarks. The art of power amplifier design is approached from a historical perspective. Power amplifiers utilizing these device technologies covering UHF through sub-millimeter wave are described including state-of-the-art amplifier benchmarks.

ADVANCES IN LINEARIZATION OF WIDEBAND (GAN) POWER AMPLIFIERS (6/14/2016)
Allen Katz, The College of New Jersey and Linearizer Technology
This presentation discusses the state of the art in achieving wideband (> 1 GHz) linearization of power amplifiers. Multi-octave bandwidth linearization has been achieved at frequencies from L through millimeter-wave bands. Basic linearization concepts are reviewed. Emphasis is placed on the use of predistortion linearization and particularly on its application with amplifiers employing GaN FET power devices. The trades between using a single predistortion linearizer and multi-band linearizers are discussed. The effect of harmonics (both even and odd order distortion products) and their correction for applications that cover more than an octave are considered.
WHAT’S NEW IN DIGITAL PRE-DISTORTION? (7/12/2016)
John Wood, Obsidian Microwave
In cellular wireless communications systems, the RF power amplifier (PA) in the transmitter must be as efficient as possible, to minimize energy costs, prolong battery life, and address “green” considerations. Modern spectrally efficient, digitally modulated signals such as LTE and UMTS present a challenge for efficient RF PA design, and the PA architectures that are adopted to achieve this goal are generally very nonlinear, requiring some form of linearization technique. This webinar shows how digital pre-distortion (DPD) linearization of PAs can address the challenges of higher spectral efficiency digital communication signals, wider bandwidth and multi-protocol signals, higher frequency radio operation, more rapid convergence in adaptive DPD (so-called “real-time” DPD), greater linearization accuracy, and the ability to accommodate memory effects. Some techniques for meeting these challenges, and ideas for new directions for DPD are offered.
SUBSTRATE INTEGRATED CIRCUITS (SICS) – A PARADIGM FOR MHZ-TO-THZ (MTT) ELECTRONIC AND PHOTONIC SYSTEMS (10/11/2016)
Ke Wu, Ecole Polytechnique, University of Montreal, and past president, MTT-S
Widespread applications and commercial success of GHz and THz electronic and photonic devices and systems—including RF, microwaves, and millimeter-waves—are closely related to their manufacturing cost and antenna-circuit integration. Our proposed integration technology of planar and non-planar structures as well as related new progress indicate that the emerging substrate integrated circuits (SICs) are able to provide unprecedented advantages for developing low-cost GHz/THz components, antennas, circuits and systems as well as wireless photonic applications. This webinar reviews state-of-the-art and underlying features of the proposed integration platforms for designing the next generation RF/millimeter-wave/THz ICs and systems. Challenges, R&D opportunities, potential problems, and possible solutions are presented.
MONOLITHIC MICROWAVE INTEGRATED CIRCUITS: DESIGN STRATEGIES FOR FIRST-TIME SUCCESS (11/8/2016)
Ali Darwish, Johns Hopkins University
The ever-expanding need for higher data rates is accelerating the development of 5G cellular systems, millimeter-wave backhaul microwave links, and ultrawide-band highly integrated circuits. Concurrently, commercial and military applications are seeking the replacement of discrete hybrid solutions with MMICs to increase performance and reduce size, weight, power, and cost (so called “SWaP-C”). The development cycle of MMICs in III-V semiconductors (e.g., GaAs, GaN, and InP) is costly and time consuming. However, a successful design can dramatically reduce the cost per unit, increase performance, and extend the reliability of the entire system. This webinar reviews the cost drivers in the MMIC development cycle, the expected cost per unit, critical active/passive modeling techniques, estimation of MMIC life-time, and instability suppression.

STANDARDS FOR 5G (PART 3 OF 3) (12/14/2016)
Sundeep Rangan, NYU Wireless
Standards will make or break the evolution and roll-out of 5G. Discussion of 5G standards so far has focused on performance targets. Specifications for communication protocols, frequencies, and hardware design appear to be fluid. This webinar helps clarify how far 5G standards have actually progressed.
DEVICE-CENTRIC ARCHITECTURES (PART 2 OF 3) (9/28/2016)
Geng Wu, Intel
In current wireless systems, data and control flow through the base station. That may change in the shift to 5G. To reduce demand on base-stations, take advantage of new (perhaps short-range) spectrum, streamline device-to-device communication, new 5G strategies may do end-runs around the base station and leaving routing, protocol, and frequency decisions to the end device. This will require new architectures, more flexible communication protocols, and (possibly) new hardware approaches to allow smart devices select the best communications options for speed, signal quality, optimizing spectrum use, and minimizing energy consumption.
PERSPECTIVES ON 5G: BEAMFORMING, MIMO, AND MORE (PART 1 OF 3) (7/14/2016)
Nuria González Prelcic, University of Vigo, & Robert W. Heath, Jr., University of Texas at Austin.
5G cannot be built on increasing high-frequency spectrum alone. To reach data-rate and user-density targets, communications strategies are moving away from the base station and migrating to the edge, creating multiple channels in single frequencies and learning how to home in on a single device in a crowded cityscape. In this session, two innovators will discuss the range of increasingly sophisticated signal processing strategies for expanding spectrum efficiency, moving from basic concepts to massive MIMO (multiple input/multiple output), mmWave MIMO, compressed channel estimation, and beamforming design.

David Gesbert & Paul de Kerret, EureCom
Developers of 5G are proposing increasingly sophisticated strategies for boosting the carrying capacity of every part of the spectrum. Approaches like beamforming, MIMO (multiple input/multiple output), and allowing devices to choose spectrum and communication protocols will put additional demands on signal processing and traffic routing at the device level. This session will outline the dimensions of the challenge and help attendees understand requirements for hardware and software performance to keep up with the information flow.

The Internet of Things is expected to be the main driver of demand for the higher information rates and lower latencies of 5G, and it will be a different world. This webinar addresses how high-bit-rate, short-range communications in ranges above 6GHz can bypass the base-station take on the local device-to-device load. Proposed allocations of the spectrum are addressed, along with strategies for coordinating IoT networks.
PERFORMANCE REQUIREMENTS FOR 5G ANTENNAS (PART 1 OF 3) (10/31/16)
Alenka Zajic, Georgia Institute of Technology
5G designers will have to devise antennas that are compact enough to fit into handheld devices or compact base-stations, flexible enough to respond to a much wider variety of frequencies over short and long distances, and smart enough to accommodate both low-data-rate spatial multiplexing (MIMO) and antenna arrays that can shape signals to deliver high data rates to a single receiver in a crowd.
