    • There is provided a power amplifier with a variable supply of bias power according to a look-up table having a voltage value determined based on a level of an RF signal being input to the power amplifier to thereby increase power efficiency. A power amplifier according to an aspect of the invention may include an amplification section amplifying an input signal according to a bias voltage being supplied; and a bias supply section comparing a level of the input signal with a look-up table set in advance and supplying a bias voltage to the amplification section according to a result of the comparison.
    • 根据具有基于输入到功率放大器的RF信号的电平确定的电压值的查找表,提供具有可变偏置电源的功率放大器,从而提高功率效率。 根据本发明的一个方面的功率放大器可以包括放大部分,其根据所提供的偏置电压来放大输入信号; 以及偏置电源部,其将输入信号的电平与预先设定的查找表进行比较,并根据比较结果向放大部提供偏置电压。
