Abstract
A circuit arrangement for amplifying radio signals between a terminal device and an antenna and to a corresponding circuit arrangement is disclosed. The circuit arrangement has a transmission amplifier path and a reception amplifier path. A signal power in a first frequency range in the transmitting direction is detected to determine a transmitted signal power and a signal power in a second frequency range in the receiving direction is detected to determine a received signal power. The detected transmitted signal power can be compared with the detected received signal power. If the detected transmitted signal power is stronger than the detected received signal power, the transmission amplifier path can amplify transmitted signals in the first frequency range. If the detected received signal power is stronger than the detected transmitted signal power, the reception amplifier path can amplify received signals in the second frequency range.
