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…
2 to 16 GHz Fundamental Symmetric Mode Acoustic Resonators in Piezoelectric Thin-Film Lithium Niobate
Vakhtang Chulukhadze, Jack Kramer, Tzu-Hsuan Hsu +5
As 5G connectivity proliferates, signal processing applications at 6G centimeter bands have gained attention for urban wireless capacity expansion. At sub-5 GHz, acoustic resonator…
Experimental Study of Periodically Poled Piezoelectric Film Lithium Niobate Resonator at Cryogenic Temperatures
Jack Kramer, Omar Barrera, Sinwoo Cho +3
This work reports the first study of periodically poled piezoelectric film (P3F) lithium niobate (LiNbO3) resonators at cryogenic temperatures. We experimentally investigate the te…
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…
23.8-GHz Acoustic Filter in Periodically Poled Piezoelectric Film Lithium Niobate With 1.52-dB IL and 19.4% FBW
Sinwoo Cho, Omar Barrera, Jack Kramer +5
This paper reports the first piezoelectric acoustic filter in periodically poled piezoelectric film (P3F) lithium niobate (LiNbO3) at 23.8 GHz with low insertion loss (IL) of 1.52…
