A tracker module is provided that includes an integrated circuit on or in a module laminate; and a plurality of external connection terminals including first to third external connection terminals. The integrated circuit includes a switch included in a switched-capacitor circuit that generates, based on an input voltage, a plurality of discrete voltages; a switch included in a supply modulator that selectively outputs, based on a first envelope signal, at least one of the plurality of discrete voltages to the first external connection terminal; and a switch included in a supply modulator that selectively outputs, based on a second envelope signal, at least one of the plurality of discrete voltages to the second external connection terminal. The third external connection terminal can be grounded and receives none of the discrete voltages. Moreover, the third external connection terminal is disposed between the first and second external connection terminals in a plan view.
