Take the frequency range calibration system of the WCDMA mobile terminal of high-pass platform as Application Example, the method that adopts calibration system to realize the calibration of WCDMA mobile terminal power to the present invention is elaborated below:
For example, requiring the frequency range WCDMA Band I of WCDMA mobile terminal at CH9613(dominant frequency 1922.6MHz) conducted power is 23.5dBm, intermediate channels CH9750(dominant frequency 1950MHz) conducted power is 23dBm, high channel CH9887(dominant frequency 1977.4MHz) conducted power is 22dBm.As follows in order to realize this object run, in the present embodiment hypothesis calibration system, actual radio frequency cable line loss is LOSS
standarddB, end objectives power is made as 23dB by software, then carries out following steps by computer:
The first step, enter calibration mode by computer control WCDMA mobile terminal;
Second step, enter the first working frequency range by computer control WCDMA mobile terminal;
The 3rd step, enter test pattern by computer control base station emulator;
The 4th step, adopt line loss table that method is set to arrange the rf signal line loss of the multiple frequency bands of WCDMA mobile terminal simultaneously;

, wherein,
the performance number that base station emulator can be read,
arrive the actual power of base station emulator prevention at radio-frequency port,
for RF line loss settings.During as the power of the transmitting of WCDMA mobile terminal herein 23.5dBm, on the radio frequency connector of base station emulator, also obtain the power of 23.5dBm, deducted after the line loss of 0.5dBm, so show in base station emulator and report the power that computer is 23dBm.
Subsequently, in the 8th step, this cover radio frequency parameter is saved, in actual conduction test, because the loss of RF cable is normal value, channel CH9613 must export the power of 23.5dBm so.Because intermediate channels calibration arranges with original the same, therefore conduct the maximum power output 23dBm that namely computer is established.
In high channel CH9887, because practical line loss is than the high 1dB of standard line loss, for base station emulator CMU200 or other instruments can be read the power output of 23dBm, WCDMA mobile terminal only needs to launch the power of 22dBm, in the 8th step, this cover radio frequency parameter is saved subsequently.In actual conduction test, because the loss of RF cable is normal value, channel CH9613 can export the power of 22dBm so.
From above-mentioned analysis, the present invention can complete WCDMA mobile terminal similar frequency bands different channels and be made as the function of different target power very easily, and this function can facilitate the debugging of WCDMA mobile terminal antenna.
