Residual Stress Anisotropy In Thin-Film Lithium Niobate For Stress-Managed MEMS
Byeongjin Kim, Ian Anderson, Tzu-Hsuan Hsu +4
In this work, we present the first experimental study of residual stress and post-release beam deflection in 128-degree Y-cut thin-film lithium niobate (TFLN) on Si, revealing pron…
An 11.7-GHz ScAlN FBAR Filter: Case Study on Scaling Limits and Challenges
Sinwoo Cho, Byeongjin Kim, Lezli Matto +9
This paper reports an 11.7 GHz compact 50 ohm ladder filter based on single layer Scandium Aluminum Nitride (ScAlN) film bulk acoustic resonators (FBARs) with platinum (Pt) electro…
Acoustic resonators above 100 GHz
Jack Kramer, Bryan T. Bosworth, Lezli Matto +8
Piezoelectric resonators are a common building block for signal processing because of their miniature size, low insertion loss, and high quality factor. As consumer electronics pus…
Thin-film scandium aluminum nitride bulk acoustic resonator with high Q of 208 and K2 of 9.5% at 12.5 GHz
Sinwoo Cho, Yinan Wang, Eugene Kwon +9
This work describes sputtered scandium aluminum nitride (ScAlN) thin-film bulk acoustic resonators (FBAR) at 12.5 GHz with high electromechanical coupling (k2) of 9.5% and quality…
Low-Loss Higher-Order Cross-Sectional Lamé Mode SAW Devices in 10-20 GHz Range
Ian Anderson, Tzu-Hsuan Hsu, Vakhtang Chulukhadze +6
This paper presents surface acoustic wave (SAW) acoustic delay lines (ADL) for studying propagation loss mechanisms in Lithium Niobate (LN). Devices were fabricated by depositing 5…
18 GHz Solidly Mounted Resonator in Scandium Aluminum Nitride on SiO2/Ta2O5 Bragg Reflector
Omar Barrera, Nishanth Ravi, Kapil Saha +12
This work reports an acoustic solidly mounted resonator (SMR) at 18.64 GHz, among the highest operating frequencies reported. The device is built in scandium aluminum nitride (ScAl…
