Abstract:
    The invention relates to a transmitter and a method of generating a transmission signal, which transmitter includes a modulation device (110) for generating two uncompensated transmission signals Y, Z by respective modulation of at least one baseband signal I, Q with an oscillation signal XLOQ, XLOI, the two uncompensated transmission signals Y, Z containing at least one respective interference component, which interference components are phase shifted by a given amount relative to one another. In accordance with the invention these interference components are eliminated by a compensation circuit that includes an all-pass 120.
