Abstract:
1. A method for enabling a power amplifier to support multiple powers, comprising: receiving radio frequency (RF) parameters delivered by a baseband board, wherein the RF parameters comprise a number of carriers that are to be amplified by the power amplifier and a power level of each of the carriers; calculating a transmit power of the power amplifier according to the RF parameters, wherein the calculating the transmit power of the power amplifier according to the RF parameters comprises calculating a transmit power level according to the number of carriers that are to be amplified by the power amplifier and the power level of each of the carriers; querying and reading a value of a supply voltage of the power amplifier corresponding to the transmit power obtained through the calculating from a list storing a corresponding relationship between a transmit power and a supply voltage of the power amplifier; wherein if the querying and reading succeed, determining the read value of the supply voltage of the power amplifier to be the value of the supply voltage of the power amplifier; and, if the querying and reading fail, determining a preset default value to be the value of the supply voltage of the power amplifier, wherein the supply voltage increases with increase of the transmit power of the power amplifier and decreases with decrease of the transmit power of the power amplifier; and adjusting the supply voltage of the power amplifier according to the determined value of the supply voltage of the power amplifier.
