Abstract: A device transmits and receives radio signals, in particular radio signals in a cellular radio network. The device contains a first transmitting antenna for transmitting radio signals and a second receiving antenna. The antennas transmit and/or receive radio signals in different frequency ranges. The antennas are connected to a common cable connection via a radio signal splitter, by which cable connection the device can be connected to a radio terminal. The device contains a first radio signal amplifier disposed in a first radio signal path and/or a second radio signal amplifier disposed in a second radio signal path. The transmitting antenna and the receiving antenna have attenuation with respect to feedback of a radio signal transmitted from the transmitting antenna to the receiving antenna due to the arrangement thereof relative to each other and due to the transmitting and/or receiving characteristics thereof.

Abstract: The transceiver according to the invention is a transmitting and receiving device for the transmission of digital signal sequences. Chirp signals are used for signal transmission by way of the air interface, such signals making it possible for the BT-product in the transmission band to be very much greater than the BT-product in the baseband by simultaneous frequency and time spreading. The transmitting and receiving device is distinguished in that chirp signals which are different in respect of the BT-product and/or the time-frequency characteristic can be stored in a memory in order for them to be selectively called up and raised into the transmission frequency band by direct upward conversion. No mirror frequency bands are produced with this procedure so that complicated band pass filters in the carrier frequency position can be eliminated.
