POWER AMPLIFICATION SYSTEM FOR RADIOFREQUENCY COMMUNICATIONS

摘要

Power amplification system (S) for radio frequency communications, comprising a input port (IN) of an input radio frequency signal (RF IN), an output port (OUT) of an output radio frequency signal (RF OUT); a digital predistortion unit (DPD) operatively interposed between the input port (IN) and the output port (OUT) and a quadrature modulation correction means (QMC IN, QMC OUT, QMC OBS) operatively interposed between the digital predistortion unit (DPD) and between at least one of the input port (IN) and the output port (OUT).
