Title:
HIGH-FREQUENCY MODULE
Document Type and Number:
WIPO Patent Application WO/2022/124064
Kind Code:
A1
Abstract:
A high-frequency module (10) comprises a module board (20), an inductor device (100), and an elastic wave filter (200). When viewed in plan view from the normal direction of the module board (20), the inductor device (100) is disposed so as to overlap with at least a portion of the elastic wave filter (200). The inductor device (100) includes a first coil (131) and a second coil (132) that are connected in series. The first coil (131) and second coil (132) are each a spiral coil or helical coil wound with more than one loop. When viewed in plan view from the normal direction of the module board, the first coil (131) is disposed such that at least a portion thereof overlaps with the second coil (132). The direction of the magnetic field formed by the first coil (131) is the opposite direction from the direction of the magnetic field formed by the second coil (132).
