Implementing average power tracking mode requires precise control of the amplifier's power output based on the frequency gap between channels, which can be challenging in dynamic communication environments.
Original Abstract Submitted
A circuit includes a power amplifier configured to amplify a first signal in a first channel and a second signal in a second channel under a condition that the first signal and the second signal are simultaneously transmitted. An envelope tracking mode is applied to the power amplifier under a condition that a frequency gap between the first channel and the second channel is less than a first threshold width, and an average power tracking mode is applied to the power amplifier under a condition that the frequency gap is at least the first threshold width.
