The invention relates to an improved method and an improved device for producing at least one transponder (33) in the satellite intermediate frequency plane and for combining said transponder with the satellite intermediate frequency band. The improved method and device are characterised in that the mixing products of the local oscillators for the lower and upper satellite bands are outside the satellite intermediate frequency bands, the transponder (33, 33a, 33b, ) is produced by means of direct conversion into the desired frequency band, and the transponder and a selected frequency band are diverted onto a cable.
