Patent number: 11936362Abstract: A thin film SAW device comprises a carrier substrate (CA), a TCF compensating layer (CL), a piezoelectric layer (PL), and an IDT electrode (EL) on top of the piezoelectric layer. A functional layer (FL) is arranged between piezoelectric layer and TCF compensating layer to further reduce the TCF. The material properties of the functional layer match those of the piezoelectric layer in view of acoustic velocity, density and stiffness such that they do not deviate from each other by more than 10% without having piezoelectric effect. The functional layer my be of the same crystalline constitution as the useful piezoelectric layer but without piezoelectric properties.Type: GrantFiled: November 29, 2019Date of Patent: March 19, 2024Assignee: RF360 Singapore Pte. Ltd.Inventors: Ingo Bleyl, Markus Hauser, Matthias Knapp

Publication number: 20220393660Abstract: 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 other performance parameters according to specifications.Type: ApplicationFiled: November 11, 2020Publication date: December 8, 2022Inventors: Matthias KNAPP, Ingo BLEYL, Markus HAUSER

Patent number: 11522516Abstract: An apparatus is disclosed for a surface-acoustic-wave filter using lithium niobate (LiNbO3). In an example aspect, the apparatus includes at least one surface-acoustic-wave filter including an electrode structure, a substrate layer, and a piezoelectric layer disposed between the electrode structure and the substrate layer. The piezoelectric layer includes lithium niobate material configured to enable propagation of an acoustic wave across its planar surface in a direction along a first filter axis. A second filter axis is along the planar surface and perpendicular to the first filter axis. A third filter axis is normal to the planar surface. An orientation of the first, second, and third filter axes is relative to a crystalline structure of the lithium niobate material as defined by Euler angles ?, ?, and ?. A value of ? has a range approximately from ?70° to ?55° or at least one symmetrical equivalent.Type: GrantFiled: August 27, 2020Date of Patent: December 6, 2022Assignee: RF360 EUROPE GMBHInventors: Ulrike Monika Roesler, Ingo Bleyl

Patent number: 9673779Abstract: An electroacoustic transducer has reduced loss due to acoustic waves emitted in the transverse direction. For this purpose, a transducer comprises a central excitation area, inner edge areas flanking the central excitation area, outer edge areas flanking the inner edge areas, and areas of the busbar flanking the outer edge areas. The longitudinal speed of the areas can be set so that the excitation profile of a piston mode is obtained.Type: GrantFiled: December 22, 2015Date of Patent: June 6, 2017Assignee: QUALCOMM IncorporatedInventors: Werner Ruile, Markus Mayer, Ulrike Rösler, Markus Hauser, Ingo Bleyl, Karl-Christian Wagner, Wolfgang Sauer, Michael Jakob, Thomas Ebner, Edgar Schmidhammer, Stefan Berek, Christoph Eggs

Patent number: 9391256Abstract: The present invention relates to an electroacoustic transducer which is arranged in an acoustic track (AS) and on a piezoelectric substrate (11) and which has two electrodes (1, 2) which are arranged on the substrate (11) and which have interengaging electrode fingers (3, 4) for exciting acoustic waves. The electrode fingers (3, 4) of an electrode (1, 2) are interconnected. The transducer also has means for increasing the mass occupation in a central excitation region (ZAB) which runs parallel to the acoustic track (AS), and the mass occupation in the central excitation region (ZAB) is higher than in an edge region (RB) which adjoins the central excitation region (ZAB) from both sides.Type: GrantFiled: December 6, 2011Date of Patent: July 12, 2016Assignee: EPCOS AGInventors: Werner Ruile, Markus Mayer, Ulrike Rösler, Markus Hauser, Ingo Bleyl, Gerd Riha, Christoph Eggs
