ABSTRACT:
Device for receiving signals, in particular radio signals, on at least two channels characterized by different carrier frequencies for each of the channels, comprising at least two receivers responsive to respective carrier frequencies and connected to a direct current electrical power supplied between at least two respective terminals. The two receivers (2, 3) are disposed in series between the two poles of a common direct current electrical power supply (13) so that one terminal of one of said receivers is connected to one pole of the power supply, one terminal of the other receiver is connected to the other pole of the power supply and their other terminals are connected together. In one embodiment, a first voltage regulator (16) regulates the voltage at the terminals of the receivers in series and a second voltage regulator (17) regulates the voltage of one of the receivers (3).
