Abstract (en)

[origin: WO2011134845A1] The invention relates to a device (1, 21, 31) for transmitting and receiving radio signals, in particular radio signals in a cellular radio network such as UTMS, LTE, and/or GSM, wherein the device (1, 21, 31) comprises at least two antennas (3, 4, 5), of which a first antenna (5) is designed as a transmitting antenna for transmitting radio signals and at least one other, second antenna (3, 4) is designed as a receiving antenna for receiving radio signals; the antennas (3, 4,5 ) are each designed for transmitting and/or receiving radio signals in a different frequency range; each of the antennas (3, 4, 5) is connected to a common cable connection (19) via a radio signal splitter (14), by means of which cable connection the device (1, 21, 31) can be connected to a radio terminal; the device (1, 21, 31) comprises at least one radio signal amplifier (7, 37, 38), wherein a first radio signal amplifier (7, 37) is disposed in a first radio signal path between the radio signal splitter (14, 34) and the transmitting antenna (5) and/or a second radio signal amplifier (38) is disposed in a second radio signal path between the receiving antenna (4) and the radio signal splitter (14); and the transmitting antenna (5) and the receiving antenna (3, 4) comprise damping with respect to feedback of a radio signal transmitted from the transmitting antenna (5) to the receiving antenna (3, 4) due to the arrangement thereof relative to each other and due to the transmitting and/or receiving characteristics thereof, said damping being greater than the amplification gain of the first and second radio signal amplifier (7, 37, 38), minus a damping comprised of the radio signal splitter (14) with respect to crosstalk of the signals between the radio signal paths.
