Abstract:
The ever-expanding demand of our interconnected world drives the global innovation of future communication systems and technologies. As our reliance on digital communication grows, there is a pressing requirement for systems that can accommodate increasing data traffic, provide faster and more reliable connectivity, and support a diverse range of applications in a sustainable way. Moving towards higher frequency bands (mm-wave and sub-THz) and more disruptive technologies, using heterogeneous integration of (Bi)CMOS, SOI, and III/V components such as GaN or InP, and advanced packaging techniques will be necessary to realize the objectives of ubiquitous, ultra-high bandwidth and low latency networks. This workshop presents the latest research roadmaps and realizations from the European ecosystem (industry, research and academia) enabling the development of future wireless, wired and satcom applications utilizing the mm-wave and sub-THz bands. We cover the entire value chain, comprising technologies, devices, characterization, architectures, circuits, 3D heterogeneous integration and packaging. We will leverage and establish synergetic interactions from/between European CHIPS JU projects SHIFT and Move2THz, the 3D heterogenous integration and packaging community and the MTT-TC9 society. With this workshop, we aim to stimulate synergetic research on advanced communication systems which become integral to driving economic growth, fostering innovation, and ensuring global connectivity that is both efficient and accessible to all.

Abstract:
As the Moore’s law is coming to an end, separating large systems into smaller chips based on their functionality is not only a cost-benefit solution but it allows the complex system to expand beyond theoretical size limits. Although chiplet technology has been around for many years, it has not been till the rise of the AI supercomputers and the accompanied unprecedented computational demand that put the spotlight on SiPs (System in Package). There are different aspects to the design of chiplets including the packaging, the high-speed chip-to-chip interconnect and the interoperability and standardization which allow the SiP built by the combination of chips from different vendors. There are multiple benefits to the chiplet-based architectures. Breaking down the large complex systems into smaller chips based on their functionality means better yields and lower cost due to the lower probability of manufacturing defects. Cost reduction can also come with customizing the process technology for each chiplet (eg using advanced nodes for GPUs and CPUs and less expensive technologies for memories and analog interfaces). Design upgrades can also be done on certain functional blocks without the need for redesigning the whole system. To take full advantage of chiplet-based architectures, the D2D (die-to-die) interface needs to be standardized. The interoperability allows the developer to use multiple vendors. In terms of the packaging, development of 3DHI (3D Heterogeneous Integration) that enables stacking up separately manufactured components, is the perfect technology choice for chiplet-based architectures. Additionally, the ever-increasing demand for high-throughput communication links and high-resolution radar sensors is driving the development of future wireless systems at higher operating frequencies. In order to support multiple functionality, the flexibility requested to those systems, is driving the adoption of large phased array antennas. Heterogeneous technologies and vertical 3D integration will play a vital role in enhancing the performance and functional density, along with reducing the size and costs, of such RF systems. In addition to the already mentioned standardization, both on the digital and RF side, 3DHI will pose a new set of technology (processes and substrates), design (MMICS, RFIC, analog, power management, passives), packaging and thermal challenges. This workshop will address some of the challenges mentioned above both from the digital and RF point of view, combining commercial and defense perspectives with state-of-the-art research in the field. Experts from industry and academia that are at the frontline of these developments are invited to address these issues and inform the audience about the latest advances in this field.

Affiliation: STMicroelectronic
Abstract:
The 6G Telecom generation forecasts mm-wave and sub-THz applications as Fronthaul and Backhaul mm-wave and sub-THz wireless links; Reflective Intelligent Surface between mini-cell station and devices mainly in mm-wave frequency range; Short distance ultra-high data-rate mm-wave and sub-THz wireless data storage transfer; Automotive Joint communication and Sensing Radars; Health and Industrial mm-wave and sub-THz Radars and imagers; and other applications which are not yet defined. A Key challenge facing us is how to manage multi-processes dies with antennas integrated in the same object, reducing losses, and then increasing power efficiency and, at the same time targeting the cost efficiency. The workshop will discuss the trade-off Power Efficiency/Cost Efficiency of different 3D assembly strategies and will try to have a picture of the most promising research in the domain, through topics which will address as III-V GaN/Si and InP/Si, with SiGe and or CMOS Heterogeneous Integration; Wafer to Wafer; Die to Wafer, Backend of line co-integration; mm-wave sub-THz packaging, including Antenna integration, Si-Interposers, organic interposers, and other packaging 3D approach. The power efficiency can be defined as the max data rate ability, with the max distance covered by the transceiver over its power consumption, the cost efficiency is max data rate ability, with the max distance covered by the transceiver over its cost. This simple relation does not take into account the cooling equipment, if necessary, the reliability, and finally the environmental impact of the different strategies. These last points are difficult to quantify at the research level.

EuMW 2023 - Workshop
Session: WM6
Organizers: Kenjiro Nishikawa / Kazuya Yamamoto
Affiliation: Kagoshima University / Mitsubishi Electric
Abstract: More than three years have passed since 5G services started in several country’s carriers. 5G sub-6 GHz services, so-called FR1 services, are rapidly becoming popular in cellular communications. However, 5G mmwave services, so-called FR2 (28 to 39GHz) services have NOT been popular still now. From a viewpoint of device technology, in the sub-6GHz base stations, GaN HEMTs are becoming a main player for higher efficiency operation, compared to Si-LDMOS. In contrast, in the mm-wave base stations, Si-based transistors, such as SiGe HBT and SOI-CMOS, contribute to the realization of most of the real FR2 systems. This workshop will introduce REAL base station techniques and their supporting REAL device techniques for 5G and beyond 5G mm-wave systems. The feature of this workshop is that the latest information of not only Si-based MIMO and related devices but also GaN-based MIMO and related devices is given at a time. The workshop attendees, therefore, will be able to learn and understand a variety of technical issues, their countermeasures, and the latest results related to base station transmitters and devices of 5G FR2 at a time. Thus, it is expected that this workshop will be very useful for 5G amplifier designers; students, beginners or less-experienced circuit/device designers as well as experienced designers engaged in circuit- and device-suppliers for use in 5G and beyond 5G systems.

IMS 2023 - Industry Keynote
Session: Th1G-4
Speaker: Jeong-sun Moon
Affiliation: HRL
Abstract:
Realizing high-performance mm-Wave 5G and beyond communication systems will require transistors with higher linearity and efficiency than current technology options. While GaN HEMTs offer excellent power density, their limited linearity and efficiency compromise overall system performance; this requires substantial DC power consumption and power back-off to circumvent. Here, we will present the linearity and efficiency of graded-channel GaN HEMTs with the linearity figure-of-merit, OIP3/PDC, of 20 dB at 30 GHz, well beyond the 10 dB rule of thumb. For power amplifier applications, a twotone PAE of 62% was obtained experimentally at 30 GHz, which is a state-of-the-art result. We find that ~3 dB back-off from peak PAE is sufficient to achieve a carrier to third-order intermodulation (C/IM3) ratio of 30 dBc. Recent Ka-band and Wband MMICs with graded-channel GaN technology illustrate their potential for future linear and efficient mmW applications. We will talk about challenges associated with accurate linearity and efficiency modeling and validation at mmW MMICs.

Session: Connected Futures Summit
Speaker: Pascal Chevalier
Affiliation: STMicroelectronics
Abstract:
Exhibiting very steep growth, the deployment of Low Earth Orbit (LEO) satellite constellations is accompanied by a significant volume of user terminals (UT). Designed to track the satellites using phased-array antennas, UTs are key components and require the use of technologies optimized to meet performance targets and ready for consumer-like volumes.
This talk will discuss how Silicon Germanium (SiGe) BiCMOS, a long-standing technology at ST, addresses UT challenges thanks to its best-in-class performance in terms of noise figure, a key parameter as it directly links system performance with effective throughput.
We will look at how ST’s SiGe BiCMOS technology is used in the RF Front-End of several hundred elements per antenna. In addition to looking at the technology serving current UT production (B9MW), we will see what is being developed for the next generation of user terminals (B55X).
IMS 2023 - Workshop

Organizers: Farid Mejdjoub / Keisuke Shinohara
Affiliation: CNRS – IEMN / Teledyne Scientific & Imaging
Abstract:
Owing to superior electrical and thermal properties of GaN-on-SiC material systems, a tremendous progress has been made on GaN-based transistor and MMIC technologies. Advanced heterostructure material designs, epitaxial growth techniques, and transistor scaling processes enabled GaN MMICs to extend their applications from microwave to millimeter-wave frequencies (up to W-band). Next-generation RF systems require high efficiency and high linearity for more complex modulation schemes to support very high data rates. The traditional trade-off among efficiency, linearity, and power density imposes performance limitations on GaN MMICs, which become more pronounced at millimeter-wave frequencies. In this workshop, world-leading experts will discuss present status, challenges, and future perspective of millimeter-wave GaN transistor and MMIC technologies, covering emerging materials and devices, device modeling, thermal management, reliability, and circuit designs.

Abstract:
The focus of the workshop is to provide an overview on transistor performance limits in terms of reliably achievable RF output power of various semiconductor technologies that are presently competing for mobile radio-frequency (RF) applications such as 5G, 6G, automotive radar and imaging, operating in the mm-wave frequency range (ie 30GHz to 300GHz). Of particular interest here are power amplifiers, oscillators, Mach-Zehnder-interferometers, and all sorts of RF buffer circuits that drive transistors to their dynamic large-signal limits and are implemented in semiconductor technologies such as III-V HBTs, SiGe HBTs and FDSOI-CMOS. The presentations will explore the presently quite heterogeneous approaches for determining the transistor related safe-operating-area in terms of reliability and ruggedness for designing circuits that are supposed to deliver high output power at high frequencies in mobile applications. The workshop starts with a tutorial on the design specifications of the above mentioned circuits and the corresponding requirements for large-signal dynamic transistor operation up to the mm-wave region. Based on this motivation, several presentations will outline, for each of the technologies, the state-of-the-art of transistor characterization for RF ruggedness as well as the device physics that cause degradation and the modeling approaches for including reliability aspects in process design kits. The workshop concludes with a tutorial on existing measurements methods for large-signal device testing in the mm-wave range.

EuMW 2019 - Workshop
Session: WS-08
Chair/Vice-Chair: Gabriele Formicone / Guillaume Callet
Affiliation: Integra Technologies / UMS
Abstract:
Latest or emerging trends in radar and communications take advantage of operation over multiple frequency bands to achieve system capabilities unobtainable through operation over a standard frequency band. One example of such trend is clearly manifested in wireless communications with carrier aggregation and multi-band front-ends. Wireless communications over multiple bands enable higher data rates and these low power systems can take advantage of the latest developments in tunable and reconfigurable components. Other examples of RF systems operating over multiple bands are dual-band transponders and transceivers for satcom or telemetry, tracking and command (TT&C). Similarly, although operating at much higher power levels compared to multi-band communication systems, a radar operating over multiple bands has the capability of providing greater functionality. For example, a radar operating at S and X band (DBR, Raytheon) or C and X band (Kronos, Leonardo), or S and C band, or X and Ka band (GEMINI-DB) can provide an unprecedented level of performance and capability to detect and track hostile targets or higher resolution and more information in remote sensing applications. Such multi-band RF systems require sub-system components such as power amplifiers, antennas, filters, switches, etc. with unprecedented design challenges. This workshop focuses on RF technologies and techniques available for power amplifiers operating over multiple bands. Being a relatively new field, power amplifier design techniques are still evolving without a fully established methodology. Moreover, although multi-band communication systems operate over relatively close multiple bands, where broadband / wideband power amplifier techniques can be quite successful, multi-band radar frequency bands tend to be very far apart where traditional broadband / wideband techniques may not yield the best performance. For instance, broadband / wideband power amplifier techniques require very expensive trade-offs in terms of efficiency, gain and power level. Therefore, innovative ideas suitable for such emerging systems are strongly desired with the potential to achieve higher RF performance metrics in terms of efficiency, gain and power level. This workshop reviews the RF and MW technologies and techniques available to the designers today, with the hope of opening a debate and stimulating new ideas and maybe identifying new directions of research and development which could lead to future multi-band high power amplifiers with superior performance than achievable today.
A tentative outline of the agenda for the workshop is the following:
1) Introduction: Multi-Band Communications and Radar Systems Requirements and Considerations
2) Review of Solid-State RF & MW technologies and Travelling Wave Tubes for Multi-Band RF PAs
3) Review of Broadband / Wideband Design Techniques for Multiband Communication and Radar Systems
4) Power Amplifier Architecture implementation: MMIC and / or multi-chip planar / hybrid module
5) Review of other components (switches, antennas, etc.) for Multi-Band RF Systems
6) Conclusions and discussions
