A circuit arrangement comprising a tuner and a splitter-modulator, the latter made up of a splitter and a modulator, the splitter having an RF signal input for receiving an RF input signal, an RF signal output for supplying an RF output signal, and a first line for applying the RF input signal to the tuner. A second line is provided for supplying an RF output signal from the modulator. The tuner is adapted to demodulate the RF input signal and the modulator is adapted to, convert a baseband signal into the RF output signal to be supplied by the modulator. Devices for generating reference oscillations for the tuner and the splitter-modulator have one quartz crystal which is common to the tuner and the splitter-modulator. This results in a reduction in the number of components, particularly for generating the oscillations.
