Spurious-Free Lithium Niobate Bulk Acoustic Resonator for Piezoelectric Power Conversion
Kristi Nguyen, Eric Stolt, Weston Braun +5
Recently, piezoelectric power conversion has shown great benefits from replacing the bulky and lossy magnetic inductor in a traditional power converter with a piezoelectric resonat…
Thin-Film Lithium Niobate Acoustic Resonator with High Q of 237 and k2 of 5.1% at 50.74 GHz
Jack Kramer, Vakhtang Chulukhadze, Kenny Huynh +6
This work reports a 50.74 GHz lithium niobate (LiNbO3) acoustic resonator with a high quality factor (Q) of 237 and an electromechanical coupling (k2) of 5.17% resulting in a figur…
Thin-Film Lithium Niobate Acoustic Filter at 23.5 GHz with 2.38 dB IL and 18.2% FBW
Omar Barrera, Sinwoo Cho, Lezli Matto +6
This work reports an acoustic filter at 23.5 GHz with a low insertion loss (IL) of 2.38 dB and a 3-dB fractional bandwidth (FBW) of 18.2%, significantly surpassing the state-of-the…
Nanoscale Imaging of Super-High-Frequency Microelectromechanical Resonators with Femtometer Sensitivity
Daehun Lee, Shahin Jahanbani, Jack Kramer +2
Implementing microelectromechanical system (MEMS) resonators calls for detailed microscopic understanding of the devices, such as energy dissipation channels, spurious modes, and i…
Visualization of Acoustic Power Flow in Suspended Thin-film Lithium Niobate Phononic Devices
Daehun Lee, Shawn Meyer, Songbin Gong +2
We report direct visualization of gigahertz-frequency acoustic waves in lithium niobate phononic circuits. Primary propagation parameters, such as the power flow angle (PFA) and pr…
A Laterally Vibrating Lithium Niobate MEMS Resonator Array Operating at 500°C in Air
Savannah R. Benbrook, Caitlin A. Chapin, Ruochen Lu +3
This paper is the first report of the high-temperature characteristics of a laterally vibrating piezoelectric lithium niobate (LiNbO) MEMS resonator array up to 500°C in air.…
