High Coupling Tunable Acoustic Resonators in Monolithic Barium Titanate
Ian Anderson, Agham Posadas, Alexander A. Demkov +1
The growing number of wireless communication bands has driven demand for compact, low-loss, and frequency adjustable RF filtering. Tunable acoustic resonators are well suited to ad…
Nonlinear Characterization of Thin-Film LiNbO3 Acoustic Filters
Omar Barrera, Bryan T. Bosworth, Taran Anusorn +10
Compact, high-performance components in millimeter-wave (mmWave) communication systems demand new acoustic filter technology at increasingly higher frequencies. Among various promi…
Lattice XBAR Filters in Thin-Film Lithium Niobate
Taran Anusorn, Byeongjin Kim, Ian Anderson +2
This work presents the demonstration of lattice filters based on laterally excited bulk acoustic resonators (XBARs). Two filter implementations, namely direct lattice and layout-ba…
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…
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…
