Title:
FILTER AND MANUFACTURING METHOD THEREFOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/044871
Kind Code:
A1
Abstract:
Provided are a filter and a manufacturing method therefor, and an electronic device. The filter comprises a dielectric substrate (10), and at least one inductor and at least one capacitor which are integrated on the dielectric substrate (10). The dielectric substrate (10) is provided with a first connection via passing through in the thickness direction thereof. The dielectric substrate (10) comprises a first surface and a second surface oppositely arranged in the thickness direction thereof. The inductor comprises a first conductive structure (21) arranged on the first surface, a second conductive structure (22) arranged on the second surface, and a first connection electrode (11) arranged in the first connection via. The first conductive structure (21) is connected to the second conductive structure (22) by means of the first connection electrode (11) to form a coil structure of the inductor. A buffer layer (3) is provided between the first conductive structure (21) and the first surface. The first conductive structure (21) is electrically connected to the first connection electrode (11) by means of the first connection via passing through the buffer layer (3).
