Abstract
Multi-mode surface acoustic wave filters are disclosed. A multi-mode surface acoustic wave filter can include a plurality of interdigital transducer electrodes that are longitudinally coupled to each other and stepped acoustic reflectors on opposing sides of the plurality of interdigital transducer electrodes. The acoustic reflectors include acoustic reflector fingers with stepped lengths.
Claims20
An acoustic wave filter comprising:
- a multi-mode surface acoustic wave filter including longitudinally coupled interdigital transducer electrodes positioned between a first acoustic reflector and a second acoustic reflector, the second acoustic reflector including acoustic reflector fingers having slanted pitches and stepped lengths;
- and
- a plurality of acoustic wave resonators coupled to the multi-mode surface acoustic wave filter, the plurality of acoustic wave resonators arranged in a ladder topology, the acoustic wave filter configured to filter a radio frequency signal.
An acoustic wave component comprising:
- an interdigital transducer electrode;
- a first acoustic reflector;
- and
- a second acoustic reflector, the second acoustic reflector positioned on an opposing side of the interdigital transducer electrode than the first acoustic reflector, and the second acoustic reflector including acoustic reflector fingers having slanted pitches and stepped lengths.
