Millimeter Wave Thin-Film Bulk Acoustic Resonator in Sputtered Scandium Aluminum Nitride Using Platinum Electrodes
Sinwoo Cho, Omar Barrera, Pietro Simeoni +6
This work describes sputtered scandium aluminum nitride (ScAlN) thin-film bulk acoustic resonators (FBAR) at millimeter wave (mmWave) with high quality factor (Q) using platinum (P…
Transferred Thin Film Lithium Niobate as Millimeter Wave Acoustic Filter Platforms
Omar Barrera, Sinwoo Cho, Kenny Hyunh +6
This paper reports the first high-performance acoustic filters toward millimeter wave (mmWave) bands using transferred single-crystal thin film lithium niobate (LiNbO3). By transfe…
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…
