Feedback control loop for amplitude modulation in a polar transmitter with a translational loop

摘要

Amplitude modulation is provided for a polar transmitter that incorporates a translational loop. The input to the polar transmitter and translational loop may be an amplitude modulated signal. The amplitude modulation of the transmitter may be controlled via a closed loop to help ensure that the output of the amplifier accurately corresponds to the modulated input signal. The transmitter may incorporate partially integrated or separate translational and amplitude modulation loops.
