1. A method of setting a transmitted power of a mobile communication device, the method comprising:

  • amplifying digital signals (I1, Q1) from a data source belonging to the mobile communication device by a digital gain by means of a controllable digital amplifier to generate amplified digital signals (I2, Q2);

    converting the amplified digital signals (I2, Q2) into analog signals (I3, Q3);

    modulating the analog signals onto a carrier frequency (fT);

    amplifying the modulated analog signals (X3) by an analog gain in at least one controllable analog amplifier to produce amplified analog signal (X4); and

    matching the digital gain (D) and the analog gain (A), as a function of a difference between a measured power signal (p(t)) derived from the amplified analog signal (X4) that represents a measurement of the transmitted power and a desired power signal that represents a desired value for the transmitted power from a base station, wherein the matching combines the digital gain and the analog gain to produce an overall gain and the desired value for the transmitted power by controlling the digital gain to minimize a contribution of the analog gain to the overall gain.
