Patent ID: 11909358
Assignee: MURATA MANUFACTURING CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A system comprising:
an RF amplifier configured to receive a RF signal at an RF input thereof;
a multi-level power supply;
a first modulator coupled to the multi-level power supply and configured to provide a first modulated power supply output signal;
a second modulator coupled to the multi-level power supply and configured to provide a second modulated power supply output signal;
means for providing split transition waveforms in which the timing of a transition for the first modulator is displaced from that of the second modulator by a time delay TD, thereby enabling a partial or full reduction of undesired energy in the combined output waveform;
a transition detect circuit to detect the direction of an impending power transition; and
a lookahead delay circuit configured to set a value of the time delay TD based on the impending power transition.
