Abstract

The invention relates to a transmitter front-end device for generating output signals representing a digital stream, wherein the device has at least one first input for a first input signal and at least one second input for a second input signal, with the first input signal and the second input signal representing a complex data signal of the digital stream and being intended to influence an output signal of the transmitter front-end device. Furthermore, the transmitter front-end device has at least one phase generation device which generates at least one additional phase signal on the basis of the first input signal and the second input signal, with at least 3 phase signals being outputted by the phase generation device with different phases with respect to each other, at least one modulator that is set up such that it generates a complementary phase signal pair from a received phase signal, with each of the at least 3 phase signals being processed by an associated modulator into a corresponding complementary phase signal pair. Furthermore, the transmitter front-end device has at least one frequency converter that is set up such that it converts phase signals of a complementary ph…
