Patent ID: 7155252

Claim:
A receive front-end module for use in a multi-band, multi-mode communication device, the communication device having a plurality of electrically separated antennas, said receive front-end module comprising: at least two feed points adapted to connect separately to at least two of said plurality of antennas for receiving communication signals in the communication device; a plurality of signal paths, operatively connected to the feed points for simultaneously receiving communication signals in a plurality of frequency bands, wherein each signal path has a filter for filtering the communication signals in the corresponding frequency band; and at least one isolation component, disposed in the signal paths, for providing cross-band isolation between at least two of the signal paths, wherein at least two of said plurality of signals paths are adapted to simultaneously receive communication signals in a plurality of frequency bands from one of the antennas through one of the two feed points, and at least a different one of the said plurality of signal paths is adapted to receive communication signals from another one of the antennas through the other of the two feed points in a further frequency band different from the said plurality of frequency bands.
