Method, rf module and test method for enabling power amplifier to support multiple powers

An Radio Frequency (RF) module, comprising a conversion module that converts a baseband board signal into an RF signal, an antenna linear device, and a power amplifier module, the RF module further comprising:

• an adjustable power module;
• a storage module, adapted to store RF parameters delivered by a baseband board and a corresponding relationship between a transmit power and a power amplifier voltage;
• a power control module, adapted to calculate a transmit power according to the RF parameters stored in the storage module, determine the power amplifier voltage according to the transmit power and the corresponding relationship between the transmit power and the power amplifier voltage, and adjust an output voltage of the adjustable power module according to the determined power amplifier voltage.

A method for determining a corresponding relationship between a transmit power and a power amplifier voltage, comprising:

• debugging a power amplifier module and an RF module to obtain the corresponding relationship between the transmit power and the power amplifier voltage;
• performing, by a production equipment, index tests on the RF module according to the power amplifier voltages corresponding to obtained different transmit powers after an aging treatment of the RF module;
• determining whether the index tests satisfy specifications, adjusting the power amplifier voltages corresponding to the different transmit powers according to results of the index tests, and updating the corresponding relationship between the transmit power and the power amplifier voltage by the use of the adjusted power amplifier voltages.
