    Abstract: A circuit arrangement for a mobile radio device includes a first transmission path for a first communication system with TDD duplex operation and a second transmission path for a second communication system with FDD duplex operation. The first transmission path contains a first transmission filter and the second transmission path contains a first duplexer. The first and second communication systems use transmission frequency bands that are arranged within the same octave. A transmitted signal from the first communication system can be routed switchably and thus either via the first or the second transmission path.

    Abstract: A module for a mobile radio device is proposed, whose central element is a multiswitch MS, which, as desired, can connect outputs for transmission and/or reception branches SZ, EZ of different mobile radio systems to an antenna ANT. The module is suitable for a multiband operation and, optionally, additional multimode operations and includes at least one pair of outputs for transmission and reception branches of a frequency duplexed mobile radio system. Between each output of the multiswitch and the antenna, a matching element is provided, which allows an electrical matching of the branches to be connected to it. The duplex operation is carried out via separate transmission and reception filters, or on the switch via separate outputs for transmission and reception branches.

    Abstract: A front-end module is for use with at least three radio frequency bands. The front-end module includes at least five signal paths, and an antenna switch to electrically connect an antenna to one of the signal paths. At least one of the signal paths includes subpaths. A frequency separating network interfaces the at least one signal path to the subpaths. The subpaths are for use in passing different radio frequency bands. The different radio frequency bands have frequency ranges that do not overlap.

    Abstract: The invention relates to a circuit comprising an antenna input (1), a signal input (2) and a signal output (3), and a switching unit (4), wherein the antenna input (1) is connected to a first protection device (6) against electrostatic discharges, said first protection device (6) being a band-pass filter in a π-configuration. The advantage of the first protection device (6) is that it eliminates the need for a band-pass filter in the front end module, when used in a mobile telephone. Furthermore, the band-pass filter has a very good filtering characteristic, enabling ESD-related disturbances to be effectively suppressed. The invention also relates to a switching module and to the use of the same.
