Abstract

A power amplification circuit (100) is provided with an input terminal (T1), an output terminal (T2), amplifiers (110, 120), a balun (140), and semiconductor substrates (241, 242). The amplifier (110) amplifies a high-frequency signal received by the input terminal (T1). The amplifier (120) further amplifies the high-frequency signal amplified by the amplifier (110). The balun (140) is connected to the amplifier (120) and converts an unbalanced line into two balanced lines. The amplifier (110) and the amplifier (120) are formed on the semiconductor substrates. One balanced line is connected to a terminal (T21) of the output terminal (T2). The other balanced line is connected to a terminal (T22) of the output terminal (T2). The frequency of the high-frequency signal to be transmitted is 100 GHz or higher. The balun (140) is formed on the semiconductor substrate (241).
