The invention relates to a power amplifier circuit, a high-frequency circuit and a communication device, which can correspond to high frequency and further reduce power consumption. A power amplifier circuit (1) is provided with a transmission circuit (2), a control circuit (3), a first terminal (4), and a second terminal (5). The transmission circuit (2) includes an amplification element. The amplification element amplifies the power of the high-frequency signal. The control circuit (3) controls the transmission circuit (2). A serial data signal is input to the first terminal (4). The serial data signal contains information based on a serial data standard. A digital signal different from the serial data signal is input to the second terminal (5). The control circuit (3) controls the transmission circuit (2) on the basis of a digital signal input from the second terminal (5). 本发明涉及功率放大电路、高频电路以及通信装置，能够与高频对应，并且进一步降低功耗。功率放大电路(1)具备发送电路(2)、控制电路(3)、第一端子(4)以及第二端子(5)。发送电路(2)包含放大元件。放大元件放大高频信号的功率。控制电路(3)控制发送电路(2)。对第一端子
