ABSTRACT:
An RF power control circuit for dividing a DC voltage by a plurality of resistors, selecting one of the partial voltages, and using the selected voltage as a reference voltage, thereby obtaining a multilevel RF output, has first and second switching circuits, controlled by an identical selection signal, each for selecting one of the partial voltages obtained by the resistors and outputting the selected voltage, and a selecting circuit for selecting one of outputs from the first and second switching circuits in accordance with a control signal.
