Patent ID: 8855574

Claim:
A radio frequency calibration method for a mobile terminal, comprising setting a parameter required for radio frequency calibration of the mobile terminal, wherein the set parameter required for the radio frequency calibration comprises: a gain level (N), a working mode of a gain of each level (R[i]), a P PDM scanning start-stop range (P PDM [i] (start), P PDM [i] (stop)) corresponding to the pain of each level, a P PDM scanning step (Step [i]) corresponding to the gain of each level, a power hot point range (HotPoint[k](start), HotPoint[k](stop)), and a power hot point P PDM scanning step (HotStep[k]), wherein N is a natural number, i represents different gain levels, i=0, 1, . . . N−1, and k represents an ordinal number of a power hot point and is a natural number; and further comprising: obtaining P PDM values of power control signals and actual output power (P) values of the mobile terminal corresponding to the P PDM values by using different scanning steps according to linearity of a power curve, or, selecting, by using different selection intervals, part of P PDM values and P values corresponding to the part of P PDM values from calibration data obtained by fine scanning; and converting the obtained P values into P AGC values recognizable by the mobile terminal, and storing the P AGC values and the P PDM values corresponding to the P AGC values into a memory of the mobile terminal.
