Abstract: A radio frequency transmitter includes a digital power amplifier and a bias control circuit. The digital power amplifier is arranged for receiving at least a radio frequency input signal, a digital amplitude control word signal and at least one bias voltage to generate a radio frequency output signal. The bias control circuit is coupled to the digital power amplifier, and is arranged for adjusting the at least one bias voltage according to a power control signal.
