ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,525,946, issued on Jan. 13, was assigned to RF360 Singapore Pte. Ltd. (Singapore).
"Thin-film saw device utilizing rayleigh mode" was invented by Matthias Knapp (Munich), Ingo Bleyl (Munich) and Markus Hauser (Feldafing, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "A surface acoustic wave device (5) is provided using a layered substrate system with a special material and a special cut of a piezoelectric thin film (4) selected for utilizing Rayleigh mode. The proper choice of the material and the cut of the piezoelectric thin film leads to a low velocity of the excited wave mode, which allows the usage of smaller devices without deteriorating o...
