9) if the second peak power detected in the step 5) is 50.2dBm, the PAR1-PAR2 is greater than the preset threshold by 0.5dB, the microprocessor reads the output average power (second average power) of the power amplifier, and controls the continuously adjustable power supply to increase the voltage of the continuously adjustable power supply until the PAR1-PAR2 is 0.5 dB; meanwhile, adjusting the ATT inside the power amplifier to keep the gain of the power amplifier at 46 dB;

10) the microprocessor judges whether the predistortion coefficient of the power amplifier is within the error range, if so, the voltage output value of the adjustable power supply is ensured, and the step 12) is entered, otherwise, the step 11) is entered;

11) the output voltage of the adjustable power supply is adjusted until the predistortion coefficient is larger than 45 and smaller than 50, so that the linearity of the power amplifier can be ensured on the basis of reducing the power consumption;
