  • RESONATOR SHAPES FOR BULK ACOUSTIC WAVE (BAW) DEVICES
    Publication number: 20230112046
    Abstract: A resonator circuit device. The present invention provides for improved resonator shapes using egg-shaped, partial egg-shaped, and asymmetrical partial egg-shaped resonator structures. These resonator shapes are configured to give less spurious mode/noise below the resonant frequency (Fs) than rectangular, circular, and elliptical resonator shapes. These improved resonator shapes also provide filter layout flexibility, which allows for more compact resonator devices compared to resonator devices using conventionally shaped resonators.
    Type: Application
    Filed: December 12, 2022
    Publication date: April 13, 2023
