Abstract
A transmission arrangement includes a step-up frequency mixer that converts a modulation signal to a transmission frequency. The step-up frequency mixer is arranged within a phase locked loop that further comprises a frequency divider that is likewise supplied with the modulation data, combined with channel pre-selection data, for the purposes of compensation. This arrangement prevents low-frequency components of the modulation signal from being eliminated by the phase locked loop. In addition, noise components and undesirable interference frequency components that are produced in the mixer are suppressed by the phase locked loop.
