A wide bandwidth power amplifier apparatus is provided. The wide bandwidth power amplifier apparatus includes a power amplifier circuit, a primary switcher circuit, a voltage circuit(s), and an auxiliary switcher circuit(s). The power amplifier circuit is configured to amplify a radio frequency (RF) signal based on a modulated voltage and a modulated current. The voltage circuit is configured to generate the modulated voltage and a respective part of the modulated current. The primary switcher circuit and the auxiliary switcher circuit are each configured to also generate a respective part of the modulated current. The auxiliary switcher circuit only generates the respective part of the modulated current when a bandwidth of the modulated voltage exceeds a bandwidth threshold. As such, it is possible to prevent the voltage circuit from having to source additional current when the modulated voltage exceeds the bandwidth threshold, thus helping to improve efficiency of the voltage circuit.
