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…
50 GHz Piezoelectric Acoustic Filter
Omar Barrera, Jack Kramer, Lezli Matto +5
This paper presents significant frequency scaling of acoustic filter technology to 50 GHz. This achievement is enabled by the P3F LiNbO3 multilayer stack, in which piezoelectric th…
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…
Practical Demonstrations of FR3-Band Thin-Film Lithium Niobate Acoustic Filter Design
Taran Anusorn, Omar Barrera, Jack Kramer +4
This article presents an approach to control the operating frequency and fractional bandwidth (FBW) of miniature acoustic filters in thin-film lithium niobate (TFLN). More specific…
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…
