Title:
WCDMA MOBILE TERMINAL POWER CALIBRATION METHOD AND CALIBRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/034044
Kind Code:
A1
Abstract:
Disclosed are a WCDMA mobile terminal power calibration method and a calibration system. The method includes: A, controlling a mobile terminal to enter a calibration mode with a computer; B, controlling the mobile terminal to enter a first working frequency band with the computer; C, controlling a base station emulator to enter a test mode with the computer; D, setting the radio frequency signal line losses of a plurality of frequency bands of the mobile terminal simultaneously; E, making the mobile terminal enter an intermediate channel, and a radio frequency amplifier sequentially entering into a high gain mode, a medium gain mode and a low gain mode, and scanning the output power of the mobile terminal and the power at an antenna port of the mobile terminal; F, calibrating the output power difference between the intermediate channel and the other channels within the first working frequency band of the mobile terminal; G, calibrating power detection circuits of the intermediate channel and the other channels under the maximum transmission power of the mobile terminal, and reading the difference; and H, modifying the working frequency band, and repeating steps B to G until the completion of the calibration of all working frequency bands supported by the mobile terminal.
