Abstract
Abstract An amplifier array having digitally adjustable total gain and being constructed of a multiplicity of switchable individual amplifiers, includes at least two parallel, selectively triggerable gain paths having input and output sides. Each of the gain paths has an input amplifier and a switching amplifier being connected downstream of the input amplifier and being switchable in stages. A multiplexer has inputs connected to the output side of the gain paths and has an output. An amplifier array input is connected to the input side of the gain paths and an amplifier array output is formed by the output of the multiplexer. In a mobile radio receiver having the amplifier array, a total gain of the amplifier array is adjusted for setting an output signal of the mobile radio receiver at a constant level.
