Next-Generation RF Filter Technologies for 6G and Wi-Fi 8

Abstract

This talk will first give an overview on advanced chip-level RF filter technologies that have been developed and commercialized during the deployment of 3G, 4G and 5G wireless communications. These include the conventional SAW, BAW/FBAR, LTCC filters, as well as the emerging IHP-SAW, XBAR and Hybrid technologies. To further enhance filter performance for 6G and Wi-Fi 8 applications, two directions of research have been pursued on next-generation acoustic resonators at the SRS lab of USTC. Lamb wave resonators based on suspended LiNbO3 thin film have been extensively studied to push the operating frequency up to mmWave bands with high performance. On the other hand, a bunch of new SAW modes (including CS-SAW, LS-SAW, and SV-SAW) have been proposed and implemented for the first time to achieve unprecedentedly high electromechanical coupling coefficient (k2 > 42%) at cmWave frequencies.

e-Tube: Data Center Connectivity Beyond Copper

Abstract

As data centers scale to meet the surging demands of AI and cloud workloads, traditional copper interconnects are reaching their physical and performance limits. 

e-Tube offers a groundbreaking solution - an RF-over-waveguide technology that delivers ultra-high bandwidth, low latency, and power-efficient connectivity over longer distances. 

Unlike copper, e-Tube maintains signal integrity at 100+Gbps per lane, enabling seamless communication between GPUs, switches, and accelerators across racks. 

With a flexible form factor and proven reliability in harsh environments, e-Tube redefines the future of data center architecture - eliminating the bottlenecks of copper and paving the way for truly scalable AI infrastructure.

Amplifying and Mobilizing Academic and Technical Leaders for Societal Impact

Abstract

Japan's wage levels rank among the lowest in the OECD, and salaries for national university faculty members are also relatively modest. Meanwhile, as Japan faces a declining birthrate and an aging population, many skilled engineers are retiring. Consequently, some companies are compelled to outsource parts of their advanced research and development. EVRIM Co., Ltd. addresses this issue by forming teams of university faculty members with industry experience to provide R&D and consulting services that meet industrial standards. This model enables faculty members to earn substantial additional income through side work. In this presentation, we will introduce the business model and discuss future developments.

Biography

Hiroyuki Ito is a co-founder and CEO at EVRIM Co., Ltd. and a professor at Institute of Science Tokyo. After obtaining his Ph.D. from Tokyo Institute of Technology, he worked as a researcher at Intel and Fujitsu Laboratories, and later engaged in research and development of high-frequency CMOS integrated circuits and IoT as an Assistant Professor and then Associate Professor at Tokyo Institute of Technology.

At EVRIM, he has been establishing business that systematically leverage the university’s intellectual property and human capital to generate mutual value for academia, industry, and faculty stakeholders, extending beyond the scope of integrated circuits.

From Bottleneck to Breakthrough: CXL Memory Expansion for AI Workstations

Abstract

AI workloads on client workstations are constrained by DRAM capacity and bandwidth. As large language models grow, inference performance can degrade by up to 90 percent. CXL memory addresses this limitation by adding scalable bandwidth and capacity, resulting in up to 25 percent faster inference with 50 percent more bandwidth. Wolley's NVMe-over-CXL Client CMM enables seamless memory expansion without compromising storage. Combined with our software-driven tiering and interleaving, this solution unlocks efficient, high-performance AI at the edge.
