Abstract:
An apparatus for determining information on a power variation of a transmit signal comprises a power amplifier module, an antenna module and a power variation determining module. The power amplifier module amplifies a radio frequency transmit signal and the antenna module transmits at least partly the amplified radio frequency transmit signal. The power variation determining module determines a weighted sum of a first feedback signal derived from the amplified radio frequency transmit signal and a second feedback signal derived from the amplified radio frequency transmit signal. The first feedback signal and the second feedback signal comprise different dependencies on a varying impedance at the antenna module. Further, the power variation determining module generates a power variation signal based on the weighted sum. The power variation signal comprises information related to a power variation of the amplified radio frequency transmit signal.
