Abstract
A tracker module is provided that includes a module laminate, an IC chip disposed at the module laminate, and a filter circuit including a plurality of inductors. The IC chip includes at least one switch included in a switched-capacitor circuit and at least one switch included in a supply modulator. The plurality of inductors include a first inductor and a second inductor that are disposed at the module laminate. The first inductor and the second inductor are adjacent to each other. A magnetic flux direction of the first inductor and a magnetic flux direction of the second inductor are perpendicular to each other.
