Title:
INTEGRATED TRANSFORMER AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/210539
Kind Code:
A1
Abstract:
Disclosed are an integrated transformer and an electronic device. The integrated transformer comprises: at least one layer of substrate (10, 210, 310, 510, 610), a plurality of magnetic cores (16, 216), a transmission line layer and a plurality of electric conductive pieces (17), wherein each substrate (10, 210, 310, 510, 610) is provided with a plurality of annular containing grooves (18) to divide the substrate (10, 210, 310, 510, 610) into central portions (12, 312) and peripheral portions (14, 314); each central portion (12, 312) and each peripheral portion (14, 314) are provided with a plurality of inner via holes (13) and outer via holes (15) through the substrate (10, 210, 310, 510, 610); the magnetic cores (16, 216) are contained in the annular containing grooves (18); two opposing sides of each substrate (10, 210, 310, 510, 610) are respectively provided with the transmission line layer comprising a plurality of wire patterns (22); the electric conductive pieces (17) provided inside the inner via holes (13) and the outer via holes (15) are connected to the wire patterns (22) on the transmission line layer in sequence to form a coil circuit, and the central portions (12, 312), the peripheral portions (14, 314), the magnetic cores (16, 216), the electric conductive pieces (17) and the transmission line layer on each substrate (10, 210, 310, 510, 610) form a plurality of transformers (110) and filters (120); and at least one transformer (110) and at least one filter (120) are electrically connected to form a group of electromagnetic assemblies (320), and each group of electromagnetic assemblies (320) are not electrically connected to each other on the substrate (10, 210, 310, 510, 610). Providing the transformer (110) and the filter (120) in the same layer can improve the signal processing efficiency of the transformer.
