Abstract: According to at least one aspect, a communication system is provided. The communication system includes a power amplifier configured to amplify an input signal to generate an amplified output signal and provide the amplified output signal to an antenna, a power supply coupled to the power amplifier and configured to provide power to the power amplifier based on a power supply control signal, and a controller coupled to the power supply. The controller is configured to identify a target transmit power level for transmission of a wireless signal, generate the power supply control signal based on the target transmit power level using information indicative of a relationship between the target transmit power level and a setting of the power supply, generate performance information indicative of a characteristic of the communication system when the wireless signal is transmitted, and update the information indicative of the relationship using the performance information.

Abstract: A matching network circuit for RF power amplifier circuit capable of odd harmonic rejection and even harmonic rejection in the differential mode and the common mode, respectively. The matching network circuit includes a differential mode filter with a differential resonant frequency and a passive component coupled to a virtual short circuit node at the differential mode filter, wherein a common mode filter with a common resonant frequency includes the differential mode filter and the passive component. As a result, two notch filters with different resonant frequencies are utilized for the common mode and the differential mode, respectively.
