ABSTRACT:
A device for amplifying signals comprising at least two amplifier circuits (20, 30, 40, 50) as well as means for precluding interference between the amplifier circuits (20, 30, 40, 50). The amplifier circuit (20, 30, 40, 50) is provided with at least first and second modules (109, 110, 112) which are arranged in cascade, each module (109, 110, 112) being provided with an earth point (i, c, p). The means for precluding interference comprise at least one global earth point (60) and a number of earth connections (70, 80, 90) between the earth points (i, c, p) of corresponding modules (109, 110, 112). The global earth point (60) is connected to the individual earth connections (70, 80, 90).
