1. An apparatus comprising:

  • a first transmission path to receive and process baseband data in a first mode of operation to generate a radio frequency (RF) signal for output via a common output path wherein generation of the RF signal includes, at a mixer, coupling baseband data to one or more mixer slices thereby providing a digital variable gain amplifier;

    a second transmission path to receive and process the baseband data in a second mode of operation to generate the RF signal for output via the common output path wherein generation of the RF signal is characterized by coupling, at a mixer, additional mixer slices at a fixed current density; and

    a multiplexer arranged to provide the incoming baseband signals to a selected one of the first and second transmission paths in the first and second modes of operation respectively.
