Surface acoustic wave filter package with tapered transducer structure
The patent application (Publication Number: US20240039507A1) describes a surface acoustic wave filter package with a unique tapered interdigital transducer structure. The structure is formed on a piezoelectric layer and includes a center portion with a taper angle a in the range of 5° to 30°, while the edge portion has a taper angle ß that is less than a. Additionally, the structure can be formed from multiple layers with different taper angles, and it may be covered by a layer with a height ranging from 5 nm to 250 nm.
Furthermore, the patent application outlines a method for forming the surface acoustic wave filter package, involving the creation of a substrate, a cavity, and the surface acoustic wave filters with the tapered interdigital transducer structure. The method includes forming the structure on a piezoelectric layer, ensuring the taper angles are within specified ranges, and potentially incorporating a cover layer of specific height. The application also mentions the use of this filter package in a mobile device with a multiplexer. Overall, the patent application introduces a novel design for surface acoustic wave filters that can potentially enhance the performance of electronic devices, particularly in mobile applications where space and efficiency are crucial factors.
