摘要： A tracker module includes a module laminate, a first IC chip, and a second IC chip. The first IC chip is disposed on the module laminate. The second IC chip is configured to control a power amplifier. The first IC chip includes at least one switch included in a switched-capacitor circuit and at least one switch included in a supply modulator. The switched-capacitor circuit is configured to generate a plurality of discrete voltages based on an input voltage, and the supply modulator is configured to selectively output at least one of the plurality of discrete voltages to the power amplifier. The second IC chip is disposed on the module laminate and coupled to the first IC chip.
