Summary:
Acoustic filters are a foundational component of the radio frequency front end (RFFE) modules that
enable today’s compact, high performance, wide bandwidth mobile phones. These passive devices are
composed of acoustic resonator networks that have a high selectivity, low-loss bandpass RF filter
response. Additionally, state-of-the-art acoustic filters have footprints of < 1 square millimeter while
operating at input power levels on the order of one Watt. In this talk, we will survey the core acoustic
filter technologies, with an emphasis on transversely excited bulk acoustic resonator (XBAR) filters. We
will discuss acoustic resonator and filter physics, and highlight the differentiating attributes that the
XBAR technology provides for Fifth Generation (5G) telecommunications and beyond.
Biography:
Bio: Dr. Gregory C. Dyer is a Principal Device Engineer and Manager at Resonant, a Murata Company. He
holds a BA degree in physics and Russian from Grinnell College and a PhD in condensed matter physics
from The University California Santa Barbara. He has over a decade of experience with research
laboratories and in industry product development, spanning the electromagnetic spectrum from VHF to
the infrared, at both the component and system levels. He is currently a core team member in the
development of transversely excited bulk acoustic resonator (XBAR) filters that achieve best-in-class
loss, selectivity, and power performance. His research interests have encompassed RF acoustic filters
and sensors, low dimensional electronic structures, applied electromagnetics, and THz and mmWave
detectors and devices. He has authored 14 peer reviewed manuscripts and has more than two dozen
patents pending in the domain of RF, mmWave, and THz device physics.
