Abstract: A tracker module includes a module laminate and an integrated circuit, a filter circuit and an output terminal arranged in or on the module laminate. The integrated circuit includes at least one switch of a switched-capacitor circuit, and at least one switch of a supply modulator. The switched-capacitor circuit is configured to generate a plurality of discrete voltages. The supply modulator is configured to generate an intermediate output by selectively switching among the plurality of discrete voltages based on an envelope signal to vary the intermediate output with the envelope signal. The envelope signal is associated with a signal to be processed by an external circuit that is out of the tracker module. The filter circuit filters the intermediate output to generate a filtered output, and the output terminal provides the filtered output to the external circuit to power the external circuit.

Abstract: A power amplifier circuit includes a power amplifier configured to amplify radio-frequency signal, a supply voltage terminal coupled to the power amplifier, and a bypass capacitor coupled between ground and a supply voltage path connecting the supply voltage terminal to the power amplifier. A supply voltage (VDET) is configured to be supplied to the power amplifier through the supply voltage terminal, and the supply voltage (VDET) is configured to vary across multiple discrete voltage levels within a single frame of radio-frequency signals. The first bypass capacitor has an electrostatic capacity equal to or higher than a specific value that is determined to cause the power amplifier circuit with the first supply voltage to have a higher efficiency than a threshold efficiency. In some exemplary embodiments, the bypass capacitor has an electrostatic capacity equal to or higher than 1.4 nanofarads.
