Abstract

Disclosed are a filter production method and a filter, which relate to the technical field of wireless communication. In the above, the filter production method includes: providing a substrate structure; producing and forming a line structure on at least one side of the substrate structure, wherein the line structure includes at least one line layer, and at least one of the line layers has at least one inductor element; and producing and forming a capacitor structure and/or a resonator structure on the side of the at least one line layer close to the substrate structure and/or away from the substrate structure, wherein the capacitor structure includes at least one capacitor element, and the resonator structure includes at least one acoustic resonator. On the basis of the above method, the problem of relatively large integrated size existing in filters produced according to the prior art can be improved.
