ABSTRACT:
An apparatus, method and computer program, the apparatus including: a modulator including a first input for receiving a data signal and a second input for receiving an output signal from a phase locked loop wherein the modulator is for modulating the output signal from the phase locked loop using the data signal and providing the modulated signal to an output for connection to an amplifier; and a phase shifter configured to result in a predetermined phase shift to the modulated signal.
