Document Type and Number:
WIPO Patent Application WO/2018/112921
Kind Code:
A1
Abstract:
Embodiments of the present application provide a filter and method for adjusting the performance of a filter, capable of quickly adjusting the performance of a filter. The filter comprises: at least two acoustic resonators; a performance adjusting structure connected to the output end of a first acoustic resonator and the input end of a second acoustic resonator, the first acoustic resonator and the second acoustic resonator being any two acoustic resonators of the at least two acoustic resonators. The performance adjusting structure comprises a capacitor structure and/or an inductor structure, and the performance adjusting structure is used for adjusting the energy coupling mode between the first acoustic resonator and the second acoustic resonator.
