Mechanical filters in electronics have come a long way since their introduction in the 1920s. Modern cell phones have more than 40 micro-electro-mechanical (MEMS) filters based on acoustic cavities formed by piezoelectric materials. In this talk, I will briefly introduce mechanical filters in electronics, outlining their essential mechanical and electrical building blocks, specifically focusing on resonators, and discussing their key performance metrics. I will then explore the latest advancements in mechanical filters, particularly those integrated into modern smartphones. Next, I will introduce the concept of tunable magnetostatic resonators and demonstrate how we apply our MEMS micromachining knowledge to develop tunable, high-performance magnetostatic wave resonators for future communication filters. Finally, I will discuss the challenges and opportunities presented by upcoming 5G and 6G communication standards and how hybrid approaches can be utilized to address these challenges.
