The utility model discloses a chip structure of a high-power base station front-end radio frequency module, and belongs to the technical field of microwave and radio frequency. According to the utility model, the structure that one digital pre-distortion element is used for processing one channel in the conventional radio frequency front end is changed into the structure that one digital pre-distortion element is used for processing a plurality of channels at the same time, so that the number of the digital pre-distortion elements is reduced to the maximum extent; the problems of high energy consumption, low processing efficiency, difficulty in later maintenance and the like caused by dense stacking of a large number of components at the radio frequency front end in the prior art are solved; on the basis, the analog pre-distortion control element and the power amplifier signal acquisition unit are matched to form a feedback link, so that closed-loop processing of feedback control is realized, interference of
