Abstract: A power amplifier circuit is provided that includes a transmission circuit, a control circuit, a first terminal, and a second terminal. The transmission circuit includes an amplifier element that amplifies power of a radio frequency signal. The control circuit controls the transmission circuit. The first terminal receives a serial data signal that is based on a serial data standard. The second terminal receives a digital signal different from the serial data signal. The control circuit then controls the transmission circuit in response to the digital signal received from the second terminal.

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.
