High-Velocity Whip-Mode Microresonator in LTOI Unimorph: Measurement Methodology and Large-Signal Characterization
Tzu-Hsuan Hsu, Zihuan Liu, Harshvardhan Gupta +6
This paper presents the design, characterization, and large-signal measurement methodology of a high-order whip-mode flexural microresonator on a lithium tantalate-on-insulator (LT…
Toward Ku-Band Surface Acoustic Wave Delay Lines on AlScN-on-Diamond with Decoupled Phase and Group Velocities
Tzu-Hsuan Hsu, Kapil Saha, Yuchen Ma +4
This work reports surface acoustic wave (SAW) acoustic delay lines (ADLs) on an aluminum scandium nitride (AlScN) on diamond platform operating in the X band and approaching the Ku…
62.6 GHz ScAlN Solidly Mounted Acoustic Resonators
Yinan Wang, Byeongjin Kim, Nishanth Ravi +13
We demonstrate a record-high 62.6 GHz solidly mounted acoustic resonator (SMR) incorporating a 67.6 nm scandium aluminum nitride (Sc0.3Al0.7N) piezoelectric layer on a 40 nm buried…
19.3 GHz Acoustic Filter with High Close-in Rejection in Tri-layer Thin-Film Lithium Niobate
Omar Barrera, Sinwoo Cho, Jack Kramer +3
Acoustic filters are preferred front-end solutions at sub-6 GHz due to their superior frequency selectivity compared to electromagnetic (EM) counterparts. With the ongoing developm…
Ku-Band AlScn-On-Diamond SAW Resonators with Phase Velocity above 8600 m/s
Tzu-Hsuan Hsu, Kapil Saha, Jack Kramer +4
In this work, an Aluminum Scandium Nitride (AlScN) on Diamond Sezawa-mode surface acoustic wave (SAW) platform for RF filtering at Ku-band (12-18 GHz) is demonstrated. Thanks to th…
Thin-film Lithium Niobate on Insulator Surface Acoustic Wave Devices for 6G Centimeter Bands
Tzu-Hsuan Hsu, Joshua Campbell, Jack Kramer +4
In this work, we investigate the frequency scaling of shear-horizontal (S.H.) surface acoustic wave (SAW) resonators based on a lithium niobate on insulator (LNOI) substrate into t…
C-Band Lithium Niobate on Silicon Carbide SAW Resonator With Figure-of-Merit of 124 at 6.5 GHz
Tzu-Hsuan Hsu, Joshua Campbell, Jack Kramer +3
In this work, we demonstrate a C-band shear-horizontal surface acoustic wave (SH-SAW) resonator with high electromechanical coupling (kt2) of 22% and a quality factor (Q) of 565 ba…
