Abstract: 

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:

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.
