Abstract
Methods and devices are disclosed for amplifying radio signals between a terminal and an antenna or an antenna connection of a circuit having an amplification unit and a detector unit, which has signal branches designed for different frequency ranges, and a power detector. A transmission signal received by the terminal is divided into at least a first signal part and a second signal part. The first signal part is applied to the signal branches of the detector unit. A frequency range of the first signal part is determined by sequential application of the signal branches of the detector unit to the power detector for evaluating a power of the first signal part. For the second signal part, the signal routing in the amplification unit is adjusted based on the frequency range determined by the detector unit. At least the second signal part is amplified by the amplification unit.
