Abstract
This disclosure relates to radio frequency (RF) amplification devices and methods for amplifying an RF input signal. To set the quiescent operating level of the RF output signal, a bias signal to be applied to the RF input signal is received prior to amplifying the RF input signal. The bias signal is amplified to generate the RF output signal at the quiescent operating level and a feedback signal is received that is indicative of the quiescent operating level of the RF output signal. Prior to amplifying the RF input signal, the bias signal level of the bias signal is adjusted such that the quiescent operating level is set to a reference signal level based on the feedback signal level. This allows for adjustments to be made to the quiescent operating level and maintain the quiescent operating level at a desired value.
