<p>A power amplification circuit includes two identical and independent power amplifiers (22) and a balance/unbalance (24) converter. The balance/unbalance converter has a balanced terminal for inputting two signals with opposite phases and an unbalanced terminal for outputting a converted signal. The balanced terminal includes a first balanced pin and a second balanced pin to which two signals with opposite phases are applied. Furthermore, the input pins of the two power amplifiers are separately connected to the balanced output pins (211,212) of an RFIC (21) to independently amplify the power of the output signal on the balanced output terminal of the RFIC, and then the output pins of the amplifiers are connected to the first balanced pin and second balanced pin of the Balun. Therefore, the power of the output signal transmitted on the unbalanced terminal is multiplied by two.</p> |
