The transmission paths, which are deactivated in a basic state of the circuit arrangement, are periodically checked in succession for the presence of a transmitted signal from the terminal with a multiplexer that forms a functional component of a detection unit and that is switched through by a controller for sequential scanning of the transmission paths for the presence of such a transmitted signal. If a signal is present, only a transmission path for the correct frequency band of the transmitted signal is activated and continuously checked for the presence of a transmitted signal.

The detection circuit forms a part of a circuit arrangement for processing or influencing received signals and transmitted signals associated with the mobile radio terminal (accessory circuit). It is involved in the accessory circuit via a switching means, which is arranged in a transmission path upstream of at least one transmission power amplifier which can be activated upon detection of a transmitted signal, and is coupled to the transmission path via a coupling element which is arranged downstream of the transmission power amplifier. At the start of the transmission burst, the whole power of the transmitted signal is first of all supplied to the detector unit before said detector unit changes over the transmitted signal to the transmission power amplifier by operating the switching means.
