Featured Webinar

High Frequency, High-Q Miniature Resonator and Filter Technologies

 
Tuesday, August 8, 2023 - 12:00 PM Eastern Time
 

Abstract:

Surface (SAW) and Bulk (BAW) acoustic wave filters form the basis of frequency control in cellular handsets. As commercial wireless systems scale to frequencies beyond the sub-6GHz 5G bands, the loss, selectivity, and power handling of these traditional acoustic resonator based filters unacceptably degrades. This talk will discuss emerging approaches for realizing miniature, high performance filters in X/Ku/K bands (8-27 GHz). We will begin by discussing the fundamental mechanisms degrading acoustic resonator and filter performance when scaling to X-band frequencies and beyond. Emerging acoustic resonator materials and device structures amenable to frequency scaling will be presented and compared to traditional approaches. The current limits and future prospects for these frequency scaling approaches will also be discussed. Finally, we will explore magnetostatic wave resonator technology as an alternative approach for realizing high performance filters in X and Ku bands.

Troy Olsson

Troy Olsson, Associate Prof. at the University of Pennsylvania

Roy (Troy) H. Olsson III is an Associate Professor in the Department of Electrical and Systems Engineering at the University of Pennsylvania. His research focuses on application of piezoelectric, ferroelectric, ferrimagnetic, and multiferroic materials in radio frequency (RF), sensing, and computing devices. Prior to joining Penn, Troy was a Program Manager in the DARPA Microsystems Technology Office (MTO), where he led multiple programs in the areas of low energy sensing and communications. From 2004 to 2014, Troy was a Principal Electronics Engineer in the MEMS Technologies Department at Sandia National Laboratories where he established research efforts in piezoelectric microdevices for processing of RF, inertial and optical signals. He received his Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor in 2004. His graduate research was in the areas of low-power electronics and sensor arrays for interfacing with the central nervous systems. Troy has authored more than 100 technical journal and conference papers and holds 32 patents in the areas of microelectronics and microsystems. He was awarded an R&D100 award in 2011 for his work on Microresonator Filters and Frequency References, was named the 2017 DARPA program manager of the year, was the recipient of the NSF CAREER award in 2019, and was the general chair of the 2022 PiezoMEMS workshop. Troy was awarded the 2022 Bell Labs Prize for his work on Memory Enhanced Computing with III-Nitride Ferrodiodes.
