Title:

Wireless Power Beaming - the Future is Now

Abstract:

Although Nikola Tesla conceived of wireless power transmission more than 100 years ago, applications of this mode of directed energy have lagged behind the use of focused RF beams for telecommunications and RADAR. W.C. “Bill” Brown’s (Raytheon) invention of the rectifying antenna (’65) and demonstration of 34 kW in beamed power (’75) established the feasibility of wireless power beaming, but many challenges remain in extending the range, power level, operational frequencies, and rectenna technologies to provide wireless delivery of continuous power, at levels of MW to GW, over extended periods. Such wireless power beaming(WPB) can play a critical role in delivering renewable power from uninhabited regions to the earth’s population centers, in extending the electrification of manned and unmanned airborne, ground, and naval vehicles with power delivered from remotely-located transmitters, and may well be a key enabling technology for powering space platforms, space exploration vehicles, and future space colonies, as well as delivering solar power from space to the power grid on earth and to remote off-grid locations.

This Keynote presentation will open with a review of Tesla’s and Brown’s pioneering work and continue with the history of WPB-based Solar Power Satellite efforts, as well as other potential terrestrial and space applications. Attention will then turn to the key components of a notional WPB system – operating in RF, mmW, or laser frequencies - and the advances required to mature WPB as a pivotal application of Directed Energy technology.

Title:

High Resolution Radar Imaging for Breast Cancer Detection: Trends and Challenges

Abstract:

With ever increasing of breast cancer, which is unfortunate, the need for diagnosis and monitoring tools, i.e., radiotherapy or chemotherapy, is felt more and more. In addition to the available clinical methods, i.e., MRI, CT scan and Mammography, it is required to develop new tools with inexpensive and portable components to increase the accessibility and reducing the queue time. Radar sensing and imagining is new and emerging technology to be enabled for biomedical applications. Ultra-wideband (UWB) has raised considerable interest due to its high resolution. UWB radar can be realized in different technologies, discrete or integrated. The miniaturization carried of the integrated system allows envisioning an antenna array made of modules in which each compact or planar antenna is directly assembled with the radar transceiver chip. A customized integrated circuit can be tailored to fulfill the requirements, i.e., operational bandwidth, dynamic ranges, etc. In this talk, we investigate the typical; system and circuit-level challenges.

Title:

Reconfigurable Power Amplifiers

Abstract:

There are a number of applications requiring power amplifiers to operate in multiple, relatively narrow frequency bands with greatly differing center frequencies. A high level of amplifier performance is required within the narrow operating bands but not outside of these bands. To cover multiple bands with a single amplifier MMIC would require either a wideband power amplifier, switched individual amplifiers or a single amplifier tuned for multiple frequency bands. Wideband amplifier MMICs are available but generally have a lower level of performance when compared to amplifiers tuned for the individual bands and are difficult to scale to higher output power levels. Wideband amplifiers also have rated gain and output power capability outside of the operating bands of interest creating a potentially undesirable situation with regard to out of band emissions, harmonic level and amplifier stability. RF switching between individual amplifiers that have been optimized for each frequency range would require a large amount of semiconductor real estate and suffer reduced performance due to the insertion loss of wideband high power RF switches. Past efforts to develop amplifiers tuned for multiple bands have achieved limited success and the approach is not commonly used.

To address this a high power amplifier circuit architecture has been developed that is electronically reconfigurable for operation in multiple frequency bands, maintains a high level of performance, can be realized in a small die size and scales to higher output power levels. The approach is compatible with modern MMIC process technology and utilizes bias and control voltage levels typical of existing RF switch and amplifier functions. This talk will start with a discussion of the realization of MMIC compatible reconfigurable circuit elements and the associated RF switch and bias circuits. A design methodology to synthesize frequency reconfigurable matching networks will then be presented. Finally, these ideas will be applied to a 25W GaN S/X-band PA MMIC design. Measured results will be presented illustrating the advantages of the reconfigurable approach over existing wideband MMICs.

Lecture: Moving Beyond S-Parameter Files: Advanced Scalable and 3D EM Models for Passive Devices

Workshop: Simulation-Based GaN PA Design: From Understanding Non-Linear Models to Complete PA Design Flows

Abstract:

Lecture Abstract:

For decades measured S-parameter data files have been the most commonly available “model” for representing passive devices of all kinds in the microwave industry. S-parameter files, while useful, ubiquitous and very portable, only represent the way a specific device behaves in the test fixture environment and test conditions used for the characterization. Physically motivated equivalent circuit models, properly developed, can be setup to scale accurately with part value, substrate properties and other parameters, such as solder pad dimensions.  This advance is a marked improvement and today used by many designers world-wide. Still sometimes circuit simulation is not sufficient for pre-build risk management for microwave/mm-wave designs involving compact topologies and dense circuit implementations. 

Accordingly, full-wave 3D Electromagnetic (EM) analysis has become a crucial step for radio frequency (RF) to account for possible electromagnetic coupling interactions between microwave components and between components and their surrounding shielding and interconnect environment. This unexpected coupling can result in performance degradation and, in turn, lead to costly and lengthened design cycles. Assembling the necessary geometry for completing full-wave analysis that includes representations of such passive devices as packaged and surface mount devices, packages and connectors, requires close collaboration, and in many cases reluctant sharing of manufacturing IP details, between vendors and customers of vendors and model providers. New technology, recently available in some simulators, such as ANSYS HFSS, allows for encrypting manufacturing IP that better enables 3D EM models to be shared with a wider design community.  The wider availability of encrypted 3D EM component model libraries, such as being developed under a new partnership between Modelithics and ANSYS, is anticipated to lead to a paradigm shift in the industry. This paradigm shift is making it much easier for designers to perform comprehensive pre-build full-wave EM analyses that reduce design risk and re-work and improve time-to-market for today’s increasingly compact and complex product form factors. 

Workshop Abstract:

This workshop will focus on the basic principles behind non-linear power amplifier design and simulation-based design methods utilizing Keysight Advanced Design System software. Examples will include a basic Class AB PA Design that addresses stability considerations and is designed against a specific set of gain, power, efficiency and VSWR considerations. Extensions to address other high-efficiency modes of operation such as Class F, Class J and Doherty amplifier configurations will be discussed briefly.  PA design simulation demonstrations will be performed using state-of-the-art non-linear GaN models available from Modelithics for a range of Qorvo GaN power transistors. Examples of successfully completed PA designs will also be presented.

Title:

Energy Efficient RF- and Millimeter-Wave ICs and Frontends for Communications

Abstract:

The talk focusses on energy-efficient RF- and millimeter-wave ICs. A SiGe millimeter-wave transceiver at 190 GHz with 50 Gb/s drawing a dc power of only 154 mW is present. A single-core CMOS analog to digital converter with a speed of 24 GS/s and 3 bit resolution is demonstrated. A 2.4 GHz receiver with a power consumption of only 3 µW using aggressive duty-cycling is outlined. Variable gain amplifier concepts are elaborated, which reduce the phase errors in vector modulators simplifying beamforming control. By fast DC/DC converter chips the power consumption of typical power amplifiers can be lowered by 50 %. Bandwidth adaptive RFICs are presented which reduce the power consumption by at least a factor of two. Finally, fully integrated bendable and stretchable thin-film transistor based wireless data transmitter and receiver frontends operating in the MHz-range are outlined.

Advances in Mutual Coupling-Based Calibration in Digital Phased Array Systems

Abstract:

As digital phased array systems become increasingly common relative to their analog counterparts, there are new opportunities to test, refine, and improve on a number of emerging techniques that make use of feedback paths afforded by the inherent mutual coupling between transmitting and receiving elements for the purposes of array calibration.  This talk will provide updates on increasingly realistic modeling to predict the performance of such schemes on real systems, seeking to determine guidelines for circuit- and system-level engineering decisions that will help achieve the ultimate goal of array self-calibration without the use of any external measurement equipment.

Driving Applications and Foundation Technologies for the Wireless Century
5G/Internet of Things (IoT) and 6G/Internet of In Vivo Things (IoIT)

Abstract:

This presentation provides a perspective on the emerging Wireless Century driven by 5G/IoT and on the contemplated 6G wireless network ---with emphasis on driving applications and foundation technologies.

The fifth generation (5G) of mobile communication systems will impact our life more than any other wireless technology by enabling a seamlessly connected society and become the Internet of Tomorrow that brings together people, data, and “things” via a myriad of new applications. This presentation will review the expected disruptive market opportunities, demanding applications, and focus on several research challenges and potential technologies needed to meet the ambitious 5G/IoT requirements for broadband networking, low-latency applications [e.g., autonomous vehicles] technologies, and Internet of Things (IoT) scenarios such as Machine-to-Machine (M2M) networking.  We will emphasize the central role of Machine Learning in optimizing the latency and throughput of cell-less and edge-based (“Fog”) network architectures, synchronization of mmWave networks, novel MAC protocols and NOMA [non-orthogonal multiple access] signal processing for increased throughput in machine-to-machine communications, and methods to enable near-instant recovery from link or nodal failures.

While there are is already much early speculation on the applications, or use cases, and technologies for 6G, in vivo wireless communications and cyber-physical networking of biomedical devices has the potential of being a key component of the sixth generation (6G) wireless networks, perhaps as part of the Internet of InVivo Things (IoIT) in advancing health care delivery. This presentation provides an overview of research on characterizing the in vivo wireless RF channel, MIMO in vivo signal processing, as well as two experimental biomedical systems that use advanced wireless communications and networking to potentially change the paradigm for minimally invasive surgery and a vectorcardiogram, that provides 24x7 diagnostic cardiac capability in a compact wearable device and uses Machine Learning to predict cardiac events.

High System Gain E-Band Link in a Wideband Aircraft-to-Ground Data Transmission

Abstract:

A wireless communication link operating in E-band at 71-76 GHz with 30 dBm of transmit power from a GaN-based solid-state power amplifier and a 3-dB noise figure of its GaAs-based receiver is employed in a data transmission with up to 9.8 Gbit/s data rate between a plane and a ground station. Flying at a height of 1000 m above ground and at distances between 5 and 12 km from the receiver, a microlight aircraft hosts the payload mounted to its wing. The highly directional link is formed by a 39.7 dBi gain Cassegrain parabolic antenna in the plane-mounted transmitter, and a 48.7 dBi Cassegrain antenna with GPS-based antenna tracking in the ground terminal. Stable data links were established with up to 9.8 Gbit/s data rate employing QPSK, 8-PSK and 16-QAM modulation.

Short Course Description

Antenna arrays are a key technology in several Electromagnetics applicative scenarios, including satellite and ground wireless communications, MIMO systems, remote sensing, biomedical imaging, radar, wireless power transmission, and radioastronomy.

Because of their wide range of application, the large number of degrees of freedom at hand (e.g., type, position, and excitation of each radiating element), the available architectures, and the possible objectives ranging from the standard radiation features (e.g.,maximum directivity, minimum side lobes, maximum beam efficiency) to the multi-physics constraints (e.g., power consumption, thermal diffusion and cooling, weight, robustness, tolerance/variantions vs atmospheric agents) until the more advances systemistic criteria (reconfigurability, multi-functionality, frequency-agility, wideband/wide-scanning, quantum properties/features, etc.), the synthesis of arrays turns out to be a complex task which cannot be tackled by a single methodology.
Despite a wide heterogeneity, most of the synthesis approaches share a common theoretical framework, which is of paramount importance for all engineers and students interested in such a topic.

The objective of the short course is therefore to provide the attendees the fundamentals of Antenna Array synthesis, starting from intuitive explanations to rigorous mathematical and methodological insights about their behavior and design. Moreover, recent synthesis methodologies will be also discussed with particular emphasis on unconventional architectures for complex communications and radar systems within a new optimality framework. More specifically, advanced methodologies and architectures will be introduced, and their application in the synthesis of linear arrays will be illustrated also with a set of "Hands on" software classes.

Recent Advances in Joint Radar-Communications Processing

Abstract:

Synergistic design of communications and radar systems with common spectral and hardware resources is defining a new era towad efficient utilization of radio-frequency spectrum. This joint radar-communications (JRC) model has advantages of low cost, compact size, less power consumption, resource sharing, and safety. Today, the JRC at the higher end of the RF spectrum, i.e., the millimeter wave (mm-Wave), is attracting significant research interest because of emerging cutting-edge radar and communications applications in this band. Major challenges in realizing mm-Wave JRC are joint waveform design and performance criteria that would optimally trade off between communications and radar functionalities. This talk will give an overview of advances in JRC with an emphasis on mmWave.

Title:

Efficient and Linear GaN Power Amplifiers for Broadband High PAPR Signals

Abstract:

This talk overviews approaches for efficient amplification of several signal scenarios with wide instantaneous bandwidths, for carriers from 2 to 20GHz. First two dual-band hybrid GaN PAs in concurrent operation are described: a 2.3/3/9GHz single-ended PA and a 3.5/5.8GHz dual-band dual-load PA. The two bands are widely separated in each case. Then an octave-bandwidth 2-4GHz hybrid PA is presented with multiple simultaneous widely-spaced signals. Finally, a 10-GHz band and 17.5-20.5GHz GaN MMIC PA with >100MHz multi-carrier signals are discussed. In all cases, the designs focus on high efficiency and linearization for multiple simultaneous signals. It is shown that dynamic supply modulation is an effective method for efficiency enhancement even for extremely broadband signals, and that both digital and analog pre-distortion can be applied to meet system demands.

Title:

The Quantum Illumination Story

Abstract:

Superposition and entanglement, the quintessential characteristics of quantum physics, have been shown to provide communication, computation, and sensing capabilities that go beyond what classical physics will permit. It is natural, therefore, to explore their application to radar, despite the fact that decoherence - caused by the loss and noise encountered in radar sensing - destroys these fragile quantum properties. This paper tells the story of "quantum illumination," an entanglement-based approach to quantum radar, from its inception to its current understanding. Remarkably, despite loss and noise that destroys its initial entanglement, quantum illumination does offer a target-detection performance improvement over a classical radar of the same transmitted power. A realistic assessment of the utility of that improvement, however, shows that its value is severely limited. Nevertheless, the fact that entanglement can be of value on an entanglement-breaking channel - the meta-lesson of the quantum illumination story - should spur continued research on quantum radar.

Title:

Integration of Filters into Phased Array Antenna Panels

Abstract:

With the ever-increasing bandwidth requirements of current and future wireless services, the radio-frequency spectral environment will continue to grow more crowded. In anticipation of this development, multifunctional radar systems that can perform multiple missions, such as air-traffic control and weather monitoring, have grown in popularity in recent years. Microwave filters are needed to protect the systems from nearby interference. In this presentation, methods for integrating microwave filters directly into the antenna array panels are presented. A comparison between using different filter implementations, such as miniaturized distributed elements, lumped elements, and quasi-lumped elements, is reported. The goal is to integrate low-loss filters without adding any volume to the array. Overall, these filters can be used to mitigate interference with minimal impact of systems sensitivity, and thus ensuring proper radar operation in the crowded electrical environments of the future.

Short Course:
Stability Analysis of Microwave Circuits

Talk:
Challenges in the Analysis of Innovative Oscillator-Based Circuits for Radar, RFID and Reconfigurable Systems

Abstract:

Short Course Abstract:

Instability is a fundamental problem in the design of microwave circuits, giving rise to an experimental behaviour qualitatively different from the expected one, which will degrade or fully disrupt the circuit performance. If the simulated solution is unstable, it will not be able to recover from the small perturbations that are always present in real life, so the solution measured for the same conditions will be different from the simulated one. Undesired behaviours include oscillations, frequency divisions, hysteresis and chaos. Their a posteriori correction is impossible in integrated technologies, whereas in hybrid technologies trial and error procedures turn out to be inefficient in most cases, since they are applied without an identification and understanding of the instability phenomenon causing malfunction. As a result, the problem will arise again in new prototypes, thus increasing the production cycles and the final cost.

The course will enable a good understanding of the stability concept and the causes of the most common types of instability phenomena, and will provide practical simulation tools for an efficient prediction of these phenomena at the design stage. The course will address the stability analysis in small- and large-signal regime. Different approaches will be presented, with emphasis on the Nyquist criterion and pole-zero identification. Qualitative changes in the circuit stability properties under variations of crucial parameters, such as input power or bias voltage, are predicted with a global stability analysis. A bifurcation is a qualitative change of stability of the circuit solution or in the number of steady-state solutions when the parameter is varied continuously. The bifurcations delimit the stable operation ranges of circuits that are not expected to oscillate, such as power amplifiers or frequency multipliers. On the other hand, they are essential in circuits of autonomous nature, such as free and injection-locked oscillators and frequency dividers, as they lead these circuits to the intended operation mode. In the course, the most common types of bifurcation will be presented and classified, so that the designer may indentify the bifurcation phenomena in measurement and simulation. It will present practical examples of instability and bifurcations in nonlinear circuits such as power amplifiers, frequency multipliers, frequency dividers and voltage controlled oscillators. The impact of instability on the circuit performance (for instance, in the measured spectrum or its response to parameter variations) will be shown, and systematic and efficient stabilization procedures will be presented.

Talk Abstract:

The talk will present recent advances in the analysis and design of compact and low consumption circuits for radar, RFID and reconfigurable systems. The new topologies take advantage of the capability of oscillator circuits to combine the inherent signal generation with specific functions, such a mixing or phase shifting. However, this function integration comes at the cost of an increase in the complexity of the circuit operation, which must simultaneously fulfill a number of mathematical conditions in a system of autonomous nature. The talk focuses on realistic and easy-to-use analysis methodologies for these novel circuits. In self-injection locked radar, the oscillator signal is transmitted to the moving target and reinjected into the oscillator with a phase modulation, induced by the target movement. In compact and low-cost RFID readers the oscillator signal is controlled with a ramp generator and transmitted through an antenna, and the variations in the oscillator load impedance, induced by the tag resonators, give rise to a modulation of the oscillator frequency. The talk will present a new analysis methodology, which makes use of an oscillator model extracted from harmonic-balance simulations and insightful analytical expressions for the description of the oscillator interaction with the environment. As another example, super-regenerative oscillators are able to replace costly amplifier chains in receivers by taking advantage of the initial exponential growth of the oscillation signal. Here they will be analyzed through the extraction of a linear time-variant transfer function in the envelope domain, from which their response to any arbitrarily modulated input signal is efficiently derived. Finally, switchless reconfigurable oscillators, of practical interest in modern multiband communication systems, will be considered.
