38.7 GHz Thin Film Lithium Niobate Acoustic Filter
Omar Barrera, Sinwoo Cho, Jack Kramer +3
In this work, a 38.7 GHz acoustic wave ladder filter exhibiting insertion loss (IL) of 5.63 dB and 3-dB fractional bandwidth (FBW) of 17.6% is demonstrated, pushing the frequency l…
Millimeter Wave Thin-Film Bulk Acoustic Resonator in Sputtered Scandium Aluminum Nitride
Sinwoo Cho, Omar Barrera, Pietro Simeoni +8
This work reports a millimeter wave (mmWave) thin-film bulk acoustic resonator (FBAR) in sputtered scandium aluminum nitride (ScAlN). This paper identifies challenges of frequency…
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…
