A transceiver front-end having a plurality of signal paths operatively connected to at least two electrically separated antennas for transmitting and receiving communication signals in a plurality of frequency bands in GSM and W-CDMA modes. If the frequency band of one signal path is partially overlapping with the frequency band of another signal path, these two signal paths are connected to two different antennas. As such, some of the switching components and matching elements in the transceiver front-end can be eliminated. As a result, the reception loss can be reduced.
