57 Zusammenfassung AB [EN] The invention relates, inter alia, to a transmitter device, in particular for a base transceiver station in a mobile radio system, which has a digital modulator (20) for making available a signal containing a phase information, and a modulation closed loop (30) having a digital phase comparator (50) operating at baseband whose first input is connected to the output of the digital modulator (20). In addition, a controllable oscillator (80) is provided for generating an RF transmission signal at a controllable transmission frequency, a device (35) which is assigned to the controllable oscillator (80) and has the purpose of converting the RF transmission signal into a baseband signal containing a phase information. The output of the converter device (35) is connected here to a second input of the digital phase comparator (50). A GSM transmitter which has such a modulation closed loop (30) exhibits, in terms of its out-band noise and interference characteristics, significantly improved properties in comparison with a GSM transmitter which does not include a modulation loop. <IMAGE>
