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.
