The method includes receiving a radio frequency (RF) input signal (102) having an amplitude and a phase, adjusting the amplitude and the phase of the RF input signal (102) to produce an adjusted RF signal (108), amplifying the adjusted RF input signal (108) to produce an RF output signal (112), and combining the RF input signal (102) and the RF output signal (112) to produce an error signal (126). Next, a power level of the error signal (126) is detected, and based on the power level, automatically adjusting a gain and a phase of the RF input signal (102) and automatically adjusting a bias of the amplifier (110).
