Document Type and Number:
WIPO Patent Application WO/2023/070332
Kind Code:
A1
Abstract:
A filter manufacturing method and a filter, relating to the technical field of wireless communications. The filter manufacturing method comprises: providing a substrate structure (S110); manufacturing and forming a circuit structure on at least one side of the substrate structure (S120), wherein the circuit structure comprises at least one circuit layer, and at least one circuit layer is provided with at least one inductance element; and manufacturing and forming a capacitor structure and/or a resonance structure on the side of at least one circuit layer close to the substrate structure and/or the side away from the substrate structure (S130), wherein the capacitor structure comprises at least one capacitor element, and the resonance structure comprises at least one acoustic resonator. On the basis of the described method, the problem of a large integration size of a filter manufactured in the prior art can be improved.
