ABSTRACT:
A modulator arrangement includes a power amplifier which receives a carrier signal and has a current control input and a voltage supply input. The modulator arrangement further includes a supply voltage modulator having an output coupled to the voltage supply input and an input coupled to the data input and a bias current modulator with an output coupled to the current control input and an input coupled to the data input. A control unit is provided which has a power control output coupled to the supply voltage modulator and to the bias current modulator to control the supply voltage modulator and the bias current modulator depending on a power control signal.
