Original Abstract Submitted

Systems and methods for pulse shaping voltage transitions in envelope tracking systems are provided. In one aspect, a radio frequency module includes a power amplifier configured to receive a radio frequency input signal and a voltage source. The power amplifier further configured to amplify a radio frequency input signal using the voltage source to generate an output radio frequency signal. The radio frequency module further includes a multi-level switch modulator configured to receive an envelope signal indicative of an envelope of the radio frequency input signal and generate the voltage source based on the envelope signal at one of a plurality of discrete voltage levels. The multi-level switch modulator is further configured to generate the voltage source using an analog component during transitions between discrete voltage levels and a digital component following the transitions.
