Abstract:
The disclosure provides a radio frequency calibration method for a mobile terminal, including: setting a parameter required for radio frequency calibration of the mobile terminal (201); obtaining PPDM values of power control signals and actual output power (P) values of the mobile terminal corresponding to the PPDM values by using different scanning steps according to linearity of a power curve, or, selecting, by using different selection intervals, part of PPDM values and P value corresponding to the part of PPDM values from calibration data obtained by fine scanning (202); and converting the obtained P values into PAGC values recognizable by the mobile terminal, and storing the PAGC values and the PPDM values corresponding to the PAGC values into a memory of the mobile terminal (203). The disclosure further discloses a radio frequency calibration apparatus for a mobile terminal. Through the solution of the disclosure, the finally obtained calibration data are more approximate to the memory space of the mobile terminal in length, so that the mobile terminal can transmit correct power by querying the calibration data when transmitting power to the outside, thereby reflecting the output characteristics of the mobile terminal more truly and improving the radio frequency output index, such as inner-loop power control, of the mobile terminal.
