Abstract
Power amplifiers, amplifier systems, and related methods are disclosed herein. In one example embodiment, the amplifier system includes a bias controller that enables fast switching between an on state bias voltage and an off state bias voltage for the power amplifier. The bias controller can transition a low impedance switch to an on state to electrically couple a first electrode of a charge holding capacitor to an input of the power amplifier. The charge holding capacitor can be pre charged with the on state bias voltage to quickly provide the on state bias voltage to the power amplifier. The bias controller can also transition the low impedance switch to an off state to couple the input of the power amplifier to the off state bias voltage.
