ABSTRACT:
A radio frequency (RF) power generator includes a first switch-mode amplifier that generates a first RF signal in accordance with a first control signal and a second switch-mode amplifier that generates a second RF signal in accordance with a second control signal. The first and second control signals determine a phase difference between the first and second RF signals. An output signal envelope is based on the first and second RF signals and the phase difference. The first control and second control signals alternate phases of the first and second RF signals.
