This full-day course addresses the fundamental topic of stability in nonlinear microwave circuits and networks (MCNs), covering concepts, qualitative analysis, simulation, and engineering design. The many unique qualitative behaviors possible in common nonlinear MCNs will be illustrated, as well as the fundamental means by which these behaviors can abruptly arise with parameter changes (termed a bifurcation). Course attendees will learn about steady-state solutions, identify instability problems through small- and large-signal stability analysis, and understand dynamical mechanisms responsible for instabilities. The primary approaches for stability analysis (classical to advanced) will be presented and compared. Practical examples of instability, stability analysis, and stabilization design will be presented for MCNs such as power amplifiers, frequency multipliers/dividers, and voltage-controlled oscillators. Finally, the vast research area on harnessing nonlinear dynamics for engineering purposes will be surveyed, providing a glimpse into future nonlinear designs. The course will include video/hardware demonstrations and several live stability analysis sessions using ADS.

Workshop participants should get a very good overview of integrated antenna performance and limitations from this workshop.
Powerful design, characterization, and implementation tools of electronic devices have become easier than ever to acquire by commercial and government entities alike. This, along with the know-how of electronic design becoming globally accessible, opens the door to various activities that pose serious security risks. Some of these activities are incentivized only by commercial interests and profit, such as counterfeiting and IP theft, and others are driven by more malicious motives such as spying on, disrupting of, or interfering with the operation of a system. Regardless of the motivation, the question of how to improve the immunity of electronic devices to nefarious activities is a pressing one. This workshop discusses the security challenges associated with the analog, RF, and power portions of electronic systems, their place in the grand scheme of hardware security, why they are particularly vulnerable, how they can be exploited, and potential ways to address their security vulnerabilities.

5G Front-End Modules (FEM) for below 6GHz and at mm-wave frequencies poses daunting design challenges to fit within the phased-array antenna element spacing constraints. The challenge is to create solutions that will meet or exceed electrical, mechanical, thermal and cost requirements for both the UE and BS use cases. The close proximity of components points to the need for optimized design to achieve signal integrity and reduced insertion losses imposed by interconnects and packaging techniques at the chip, module, and board levels. This workshop will address design and manufacturing techniques by bringing together the subject matter experts from the IEEE EPS and the MTT-S communities. The workshop will highlight advances in the 2.5D/3D multichip module (MCM) integration from leading Outsourced Assembly and Test (OSAT) foundries, advanced materials, Antenna in Package (AiP) versus Antenna On Chip (AoC) trades, novel integrated circuits, beam-forming techniques, and EDA tools for co-engineering to realize high-performance 5G FEMs.
In modern communications systems, receivers are required to detect and receive very small signals, and at the same time not add a significant level of noise, otherwise the information contained within the signals may be overpowered and become unusable. In order to minimize the amount of added noise, low-noise circuit design becomes critical, and highly effective designs begin with accurate noise parameters or noise models. Noise parameters measurements and noise model extraction are extremely sensitive techniques, and the measurement/extraction system can itself become the dominant contributor of noise if the system is not calibrated accurately. Therefore understanding the sources of error, and using the best techniques and practices, is critical when attempting to accurately characterize noise parameters and extract a noise model. This short course aims to demystify noise parameter measurements and model extraction, and includes topics such as: an introduction to noise figure and noise parameter concepts; noise parameter calibration; measurement and extraction techniques and best practices; how to validate noise parameter data; an in-depth review of critical variables that affect the accuracy of noise parameter measurements; noise parameter de-embedding; and noise model theory and extraction.

Frequency synthesis plays a key role in virtually all present-day commercial, industrial and test and measurement systems. State-of-the-art low-noise frequency synthesis is a particularly important technical asset to high-speed telecommunications, efficient management of the wireless spectrum and high-resolution imaging. Overall performance of various technologies depends on, and is often limited by, phase and amplitude noise fluctuations in oscillators and frequency synthesizers. This full-day workshop will focus on modern low phase noise oscillator and frequency synthesizer techniques. The RF/microwave industry feels persistent pressure to deliver higher performance, higher functionality, smaller size, lower power consumption and lower cost synthesizer designs. Various synthesizer architectures along with their main characteristics will be analyzed. The new market demands, design challenges and possible solutions will be discussed. In respect to phase noise performance, synthesizer designers primarily rely on ovenized crystal oscillators (OCXO), which will be reviewed in detail. Longer-term major breakthroughs are expected operating the reference with other physical principles or materials. For example, the phase noise exceeding -170dBc/Hz at 10kHz offset at 10GHz output for a sapphire resonator based oscillator has been reported. These quality expectations will dramatically change conceptual approaches for building new synthesizers or even the whole way of thinking about this problem. State-of-the-art low-phase-noise oscillator techniques including sapphire loaded cavity oscillators, optoelectronic and atomic methods will also be covered.
5G spectrum is presently open world-wide to sub-6GHz and mm-Wave bands at 26GHz, 28GHz, and other bands at 40GHz, 60GHz (V) and 71-86GHz (E) are under evaluation in most parts of the world. Different power amplifier architectures and process technology approaches are in competition to cover these 5G opened bands. This workshop will benchmark the state-of-the-art power amplifier techniques targeting mm-Wave frequency for 5G applications, and will present the status of different processes addressing the Power Amplifier applications such as silicon based, III-V, GaN and InP technologies. Finally we will discuss the match between these technologies’ specificities and the different 5G application requests.
The design of future communication systems poses several challenges in terms of required bandwidth, power, efficiency, and costs. The workshop aims at discussing how these challenges can be tackled by adopting skills and techniques that, although acquired by the microwave community, are still too fragmented. More specifically, the workshop will focus on measurements, which are a crucial step at each design level, from semiconductor devices to circuits and systems. Speakers will show how a deep understanding of the measurement quality is of critical importance and remains an unavoidable step for the design of the next-generation microwave circuits and systems. Emphasis will be placed on wideband measurements accounting for new modulation techniques. Finally, different examples of circuit and system designs oriented to 5G and IoT applications will be presented. It will be emphasized how simulations and measurements merge together in modern design techniques to give rise to first-pass design strategies.

Power amplifiers are limiting components due to their energy consumption, bandwidth limitation, and gain limitation. This workshop will focus on recent innovations in power amplifier IC design techniques with specific emphasis on their realization at mm-wave frequencies. These include design and layout techniques for efficiency enhancement, linearity improvements, thermal management, memory effects, and bandwidth and gain extension. Many of these state-of-the-art improvements can be linked to power amplifier device technology whose great variety will be covered including SOI, GaN, GaAs , SiGe, and CMOS as those differ drastically in their active and passive capabilities and available design features.
As radio integration proceeds apace for 5G, satellite and other applications, over-the-air testing requirements are increasing dramatically. This workshop covers topics related to both measurement fundamentals (spatial data fusion, calibration and synchronization concerns, traceability, etc.), to the structure and measurement requirements of the subsystems being analyzed and to more advanced topics (e.g., MIMO test beds, higher order measurements such as EVM). Even simple transmission phase measurements versus position/angle can be a challenge with disjoint frequency converters and path characteristics changing over the modulation bandwidth. Nonlinear characterization (including emulated load pull) is increasingly needed for the embedded power amplifiers in these systems. Some subsystems under test may employ multibeam scanning or element-level predistortion that require additional characterization considerations. Attendees at this workshop will hear some of the latest thinking in OTA measurements and procedures and how some recent changes in integrated radio/system designs will further influence the measurement landscape.
RFID technology is today widely deployed in industrial and commercial environments with mature hardware concepts. Nevertheless, recent research demonstrates substantial potential to boost especially the achievable accuracy for RFID based localization systems and high-speed communication networks. These advances are primarily enabled through the combination of powerful digital signal processing (DSP) techniques with flexible reader hardware based on software-defined radios. Thus the most promising DSP techniques will be covered: Based on high performance wideband software defined radio platforms with modern self-interference cancellation techniques, novel modulation formats optimized for RFID scenarios in order to boost data rate as well as ranging capability will be explored. Finally, combining several nodes with unprecedented performance into a complete RFID-based communication network enables novel localization techniques, e.g., for autonomous indoor navigation. The workshop brings together all major DSP-based approaches in order to push forward their application in practice and to explore mutual benefits of their combination.
The Workshop addresses important challenges faced by the notions of reciprocity, time-reversal symmetry and sensitivity to defects in wave propagation and field transport by discussing disruptive ways in which devices and circuits are employed enabling new functionalities at high frequencies. Reciprocity can be broken, and nonreciprocal components can be built in CMOS using linear periodically time-varying circuits. Acoustic wave based integrated circuits will be described leading to time correlations and multipath equalizations directly at RF with almost no noise penalty. Various types of circulators for full-duplex and 5G mm-wave applications will be reported. Nonreciprocity considerations include one-way transport of electrons with certain spin in crystals such as topological insulators, magnetic heterostructures such as giant interfacial interaction and voltage-controlled magnetic anisotropy, magnet-free nonreciprocal and topological devices and metamaterials based on spatio-temporal modulation, self-biased magnon crystals, two-dimensional layered materials with no magnetic bias as applied to plasmonic isolators and nonreciprocal leaky-wave antennas.
The workshop aims to explore challenges and benefits of design and integration of RF/microwave devices that employ novel magnetic materials and fabrication techniques.

Integration of magnetic components on semiconductor-based platforms will be discussed, including material deposition, fabrication, and packaging methods as they relate to integrated magnetic devices. Micro- and nanomachining, hetero-epitaxial integration, and conventional solid-state chemistry approaches will be considered. The cutting-edge and comprehensive multi-physics-based modeling approaches and the corresponding experimental data for both linear and non-linear magnetic devices, e.g., RF circulators, isolators, frequency selective limiters, and signal-to-noise enhancers, will be presented. Factors limiting such RF/microwave performance criteria as bandwidth, dynamic range, noise figure, intermodulation distortion, and temperature stability will be discussed along with methods to overcome these limitations and improve the performance of such devices.
Next generation applications, including 5G and beyond, demand integration of higher speed and bandwidth RF functions into smaller volumes, yet with unprecedented levels of power and cost. For addressing these, mm-Wave and Terahertz have found an ever-increasing interest. However, as frequency increases, conventional integration lacks the geometric and interconnecting resolution, and the interconnection parasitic and losses between ICs add up quickly. The 3D heterogeneous integration technologies, employing precise wafer-scale/lithographic integration of III-V with Si semiconductors are demonstrating high suitability for these requirements. This workshop will discuss the current trends and state-of-the-art developments in 3D heterogeneously integrated multifunction circuits and modules, including integrating InP-HBT on Si/BiCMOS, and GaN-HEMT and InP-HBT on SiGe BiCMOS. Improved InP HBT integrated circuit process, BiCMOS controlled InP HBT oscillator for mm-Wave and THz beamforming, novel materials, and thermo-mechanical challenges will be discussed. Further, this workshop will present advanced micromachined and 3D-FOWLP integration and packaging covering 70GHz to THz.
In this half-day workshop we discuss several aspects of the Remote Radio Unit (RRU). This is a remote radio transceiver that is located on the radio mast and is connected to the baseband unit (BBU) typically via a fiber interface. The RRU should support data rates of tens or hundreds of Gbps and MIMO operation. This poses challenging requirements for RF front-ends and antenna beamforming. Therefore, RRU has become one of the most important sub-systems in the distributed fronthaul architecture. Distinguished speakers from leading companies from industry and academia discuss several aspects of 5G infrastructure with a focus on challenges related to the hardware implementation of RF Front-End Modules (FEMs) and beamforming techniques for RRU. Additionally, a vision of 5G wireless networks will be provided. A brief concluding discussion will round-off the workshop to summarize the key learnings and discuss the future trends in radio access networks.
The workshop addresses the “electroceutical” topic: a multidisciplinary initiative for medical treatments using electric/magnetic/electromagnetic power to modulate different body functions controlled by neurological circuits. These functions span from control of neuro-disorders, to heart pathologies, endocrine or metabolic dysfunctions. The workshop will cover the technological aspects, and will provide updated knowledge on modelling interactions between the stimulating signals (in a wide band of frequencies) and the targeted organs, down to the network of neurons. In the workshop, new technological applications related to flexible electronics (at radiofrequency-RF and microwaves-MW) and implantable devices will be proposed, including the use of nanosecond pulsed electric fields to target deep body regions with the new paradigm of the electric pulse bipolar cancellation effect. Advanced modelling of tissues and organs will be proposed under these stimulations to provide the so-called “dose-effects” curve as a meter for controlled and personalized treatments.
Next-generation wireless networks require a denser spatial distribution of base stations and a simultaneous usage of several antennas (MIMO). Moreover, frequency and service agility of the hardware components as well as integration of the RFPAs into the antenna and high frequency operation are pursued trends to fulfill the future requirements. As a result, the RFPAs need to satisfy the following essential requirements: high energy efficiency over a wide dynamic range of output power, supporting large bandwidths, while maintaining a small form factor and flexibility. In this workshop, international industry and academic experts will discuss demands and various perspectives with regard to efficient, extremely broadband and highly linear system and circuit design techniques suitable for future wireless communications in 5G and beyond.

The talks will tackle different approaches to implement front-ends in communication systems in the microwave bands. A brief discussion will conclude the workshop summarizing the key issues addressed during the day. The attendees will be encouraged to put questions and to discuss design issues that they may have.
Many wireless systems could benefit from the ability to transmit and receive on the same frequency at the same time, which is known as In-Band Full-Duplex (IBFD) and/or Simultaneous Transmit and Receive (STAR). This technology could lead to enhanced spectral efficiency for future wireless networks, such as fifth-generation New Radio (5G NR) and beyond, and/or could enable capabilities and applications that were previously considered impossible, such as IBFD with phased array systems. In this workshop, experts from academic and federal research institutions will discuss the various approaches that can be taken to suppress the inherent self-interference that is generated in IBFD systems, and will present both static and adaptive techniques that span across the propagation, analog and digital domains.

Remarkable advances in the available computational power over the past few years, and those anticipated to come, have propelled machine learning algorithms (some developed decades ago) to the forefront of R&D in a wide and diverse range of fields: from medicine to autonomous vehicles and robotics. As the interest in these algorithms deepens, new algorithmic and theoretical developments are reported and applications are explored. These are assisted by the availability of open-source software tools and libraries, such as Google’s TensorFlow and PyTorch. This workshop is a first step towards exploring the relevance and importance of machine learning for microwave engineers, and their CAD tools as used in industry and academia. We are combining a review of the field, its rich past in the microwave community (where artificial neural networks (ANNs) have been used as tools for microwave device modeling for many years) and its prospects, as developments in “deep learning” push the envelope of traditional ANNs even further, creating new opportunities to be harnessed.
