Abstract
An apparatus is disclosed for implementing an acoustic filter having an embedded electrode structure with particular geometric properties. In an example aspect, the geometric properties of the embedded electrode structure can be tailored to enhance performance of the acoustic filter in terms of insertion loss, temperature stability, quality factor, and spurious-mode suppression. Furthermore, the geometric properties can enable the acoustic filter to be tuned for a particular frequency range and/or bandwidth, to fit within space-constrained devices, and improve the ease of manufacturing. Various performance improvements and design requirements can be met using the embedded electrode structure because the geometric properties of the embedded electrode structure provide additional degrees of freedom in designing the acoustic filter. This design freedom enables a performance of the acoustic filter to be optimized in the presence of multiple complex interdependencies.
