Abstract
There is provided a power amplifier module having a bias circuit, in which a bias power is supplied to an amplifier by differently setting an impedance between an input signal terminal and a reference power terminal and an impedance between the input signal terminal and a ground. The power amplifier module includes: an amplifier unit receiving a bias power to amplify an input signal; and a bias unit supplying the bias power to the amplifier, by differently setting an impedance between an input signal terminal transmitting the input signal therethrough and a reference power terminal transmitting a reference power having a predetermined voltage level and an impedance between the input signal terminal and a ground.
