This session highlights recent innovations in acoustic wave technologies for next-generation communication systems. It covers the design of low-loss SAW filters with wide bandwidths for Wi-Fi 7, as well as frequency and bandwidth optimization of mm-wave thin-film lithium niobate acoustic filters. Additionally, the session introduces miniature, high-coupling resonators based on lithium niobate thin films operating in the 10–30GHz range. The final presentation focuses on a 36GHz periodically poled FBAR with a trilayer piezoelectric material structure, offering promising applications in high-performance frequency devices. These advances demonstrate significant potential for future wireless technologies.
