Abstract

A power amplifier, a power amplifier system, and an operating method thereof are provided. The power amplifier system may include a power amplifier, a power amplifier controller, and a voltage generator. The power amplifier may include a plurality of power transistor cells each of which receives an RF signal through a control terminal thereof to amplify the RF signal. The power amplifier controller may control turn-on and turn-off operations of at least one power transistor cell among the plurality of power transistor cells based on a power mode. The voltage generator may generate a power supply voltage supplied to first terminals of the power transistor cells and may change the power supply voltage depending on the power mode.
