Abstract
A transmission arrangement is disclosed in which two different signal paths are provided for two operating modes, in order to couple a baseband signal processing unit to a radio-frequency mixer for transmission of the modulation signal. In a first operating mode, the frequency mixer operates as a step-up frequency mixer, and converts a baseband modulation signal to radio frequency. In a second operating mode, a frequency generator is supplied with a signal that is dependent on the modulation signal and is just amplified in the frequency mixer. The described transmission arrangement supports both the conventional GSM standard and the extended GSM EDGE with higher transmission rates. The transmission arrangement in this case has good noise characteristics with a low power consumption.
