摘要
PURPOSE: A power amplifier is provided to improve maximum linear power point in a communication requiring high linearity such as WLAN communication. CONSTITUTION: A transfer wire conversion part (120) has or first transfer wire connected to the ground, and a second transfer wire receiving a first source voltage and a second source voltage. A differential amplification unit (110) outputs reverse output signals by amplifying difference between the first source voltage or the second source voltage. The differential amplification unit includes a first driving unit, a second driving unit, and an amplification end. The first driving unit connects a first transistor or a second transistor in parallel. A second driving unit connects a third transistor or a fourth transistor. An amplifier outputs signal from a first driving end or a second driving end adjustment circuit part by amplifying output signals. A matching circuit (130) integrates and outputs reverse output signals from the differential amplification unit.
