Abstract: Systems and method provided herein relate to reducing distortion of signals introduced by components on a phase path of a radio frequency system polar architecture. To reduce phase path distortion, a pre-distortion is introduced prior to a distortion caused by the components on the phase path. The pre-distortion in conjunction with the component distortion results in a transmission signal that forms its expected shape.
