Abstract
Power amplifier systems with a switchable transistor array and a switchable biasing circuit are provided herein. In certain embodiments, a power amplifier system includes a power amplifier that amplifies an RF signal, and a biasing circuit that controls a bias of the power amplifier. The power amplifier includes a transistor array in which a number of active transistors that amplify the RF signal changes based on a selected power mode of the power amplifier system. Additionally, the biasing circuit changes the bias of power amplifier based on the selected power mode. For instance, the biasing circuit can change an amount of bias current and/or a bias voltage level of the power amplifier based on the selected power mode, for instance, a low power mode or a high power mode.
