ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,562,712, issued on Feb. 24, was assigned to RF360 Singapore Pte. Ltd. (Singapore).
"Ultra-high frequency micro-acoustic device" was invented by Michael Smirnow (Munich), Werner Ruile (Munich) and Matthias Knapp (Munich).
According to the abstract* released by the U.S. Patent & Trademark Office: "A micro-acoustic wave device is proposed for application in ultrahigh frequency range. The device uses a thin film piezoelectric material stacked on a carrier substrate. Additionally, a material is embedded between carrier substrate and piezoelectric thin film that decouples the acoustic of these layers. With this approach it is possible to achieve very high Q factor even for longitudinal wav...
