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.
