| 1. A circuit arrangement for transmitting and receiving radio signals, comprising:
an amplification device including an output terminal for transmitting signals, and a supply terminal; and
an antenna for transmitting and receiving signals, the antenna connected to the output of the amplification device;
wherein a signal received by the antenna is provided to the output terminal of the amplification device, and wherein the amplification
device is configured to convert the signal into a converted signal received at the antenna and passed therethrough via the
amplifier output terminal and provide the converted signal to the supply terminal of the amplification device.
