This invention concerns a repeater for radio frequency signals. The repeater at least includes: - a channel filter (71); an active filter (70) connected to the channel filter output, covering the - channels adjacent to the channel filter (71) comprising: an amplifier (51) the output of which forms the output of the said filter; - two bandpass filters (521, 522) in parallel connected as a negative - feedback loop around the amplifier, with a first bandpass filter (521) covering the lower adjacent channels and a second bandpass filter (522) covering the higher adjacent channels. The repeater can also include: - a circuit (3, 4) converting the radio frequency signal into an intermediate frequency, with the channel filter (71) filtering the signal converted into an intermediate frequency; a circuit (3, 5) converting the signal into an intermediate frequency at - its original frequency. The invention notably applies to the development of domestic repeaters for mobile terminals meeting the DVB-H digital television standard.
