摘要：
本发明在维持功率放大器的特性的同时，使功率放大器小型化。功率放大器(1)包括：放大元件(11、12)、偏置电路(13)、公共电源端子(P6)、以及电阻(R1)。偏置电路(13)与放大元件(11、12)相连，并将偏置电压提供给放大元件(11、12)的输入端子。偏置电路(13)及放大元件(11)的输出偏置端子与公共电源端子(P6)相连。电阻(R1)连接于偏置电路(13)与公共电源端子(P6)之间。
摘要（英）：

The invention miniaturizes a power amplifier while maintaining the characteristics of the power amplifier. A power amplifier includes amplifying elements (11,12), a bias circuit (13), a common power supply terminal (P6), and a resistor (R1). The bias circuit (13) is connected to the amplifying elements (11,12) and supplies a bias voltage to an input terminal of the amplifying elements (11,12). The bias circuit (13) and an output bias terminal of the amplifying element (11) are connected to the common power supply terminal (P6). The resistor (R1) is connected in series between the bias circuit (13) and the common power supply terminal (P6).
