Abstract
A radio frequency (RF) power amplification circuit including a power amplifier is provided for preventing breakdown of the power amplifier. The power amplifier includes an input for receiving RF signals and an output for providing amplified RF signals. The RF power amplification circuit also includes a bias circuit coupled to the input of the power amplifier to permit normal operation of the power amplifier when the base current is below a predetermined current threshold and to prevent normal operation of the power amplifier when the base current is above the predetermined current threshold.
