Publication number: 20220239281Abstract: Aspects of the disclosure relate to wireless communication, and high-frequency filters with resonators. One example is a frequency band filter circuit having a split resonator. The split resonator comprises a resonator including a first section of a shared input busbar, a first section of a shared output busbar, and an electrode structure between the first section of the shared input busbar and the first section of the shared output busbar, the electrode structure configured for a resonance. The split resonator also comprises a detuned resonator. The detuned resonator includes a second section of the shared input busbar, a second section of the shared output busbar, and a detuned electrode structure between the second section of the shared input busbar and the second section of the shared output busbar, the detuned electrode structure configured for a detuned resonance different from the resonance.Type: ApplicationFiled: January 22, 2021Publication date: July 28, 2022Applicant: RF360 EUROPE GMBHInventors: Jiman YOON, Jürgen KIWITT, Robert KOCH, Maximilian PITSCHI, Gerhard KLOSKA

Patent number: 10298202Abstract: The invention relates to a BAW resonator with reduced heat build-up. The heat build-up is reduced by a thermal bridge, which dissipates heat from the electro-acoustically active region to a support substrate, without impairing the acoustics of the resonator.Type: GrantFiled: November 10, 2015Date of Patent: May 21, 2019Assignee: SnapTrack, Inc.Inventors: Andreas Tag, Bernhard Bader, Maximilian Pitschi

Patent number: 10049812Abstract: A circuit arrangement can be used for adapting the electroacoustic properties of an electroacoustic component. The circuit arrangement includes a first conductor loop and a further element. The first conductor loop includes a main loop and a negative feedback loop. The negative feedback loop has a sense of curvature that is opposite to a sense of curvature of the main loop. The negative feedback loop compensates for a coupling between the main loop and the further element.Type: GrantFiled: November 27, 2013Date of Patent: August 14, 2018Assignee: SnapTrack, Inc.Inventors: Jürgen Kiwitt, Robert Koch, Maximilian Pitschi

Patent number: 9577605Abstract: An RF component can have a reduced electromagnetic internal coupling and may be suitable for miniaturization as a result. The component includes a micro acoustic filter of ladder-type design in a housing and a double coil having a first coil segment and a second coil segment. The two coil segments are oriented in opposite directions. The two coil segments are arranged without crossover in one layer and the double coil is arranged in proximity to a parallel branch resonator of the ladder-type filter structure.Type: GrantFiled: April 15, 2014Date of Patent: February 21, 2017Assignee: EPCOS AGInventors: Robert Koch, Jürgen Kiwitt, Maximilian Pitschi

Patent number: 9362884Abstract: The invention relates to a micro-acoustic filter having a first and a second converter, in which the electromagnetic and capacitive cross-talk between the first and second converters is compensated for by providing additional coupling capacitors and additional current loops. Additional coupling capacitors and current loops are arranged in such a manner that they can counteract the sign of the natural coupling specified by the design and thus completely compensate for said coupling.Type: GrantFiled: February 14, 2011Date of Patent: June 7, 2016Assignee: EPCOS AGInventors: Guillermo Moreno Granado, Jürgen Kiwitt, Maximilian Pitschi, Tilo Gärtner
