    • A receive front-end module in a multi-band communication device. The communication device comprises a plurality of signal paths for receiving and transmitting communication signals in a plurality of frequency bands in GSM and W-CDMA modes. The signal paths in the receive front-end module are operatively connected to a common feed point, which is connected to one of the RF antennas of the communication device, and the signal paths are selected such that no frequency bands for receiving communication signals in the receive front-end module are overlapping. If the communication device also transmits the communication signal in at least one transmit frequency range partially overlapping with one of the frequency bands in the receive front-end module, switching means is provided to at least one of signal paths in the receive front-end module for providing cross-band isolation between the transmitted and received communication signals.
