1. A radio frequency front-end system comprising:
a first broadband radio frequency module including a first switch, a first bandwidth controllable transmit filter coupled to the first switch and configured to selectively filter a first frequency band or a second frequency band, a first bandwidth controllable receive filter coupled to the first switch and configured to selectively filter the first frequency band or the second frequency band, and a second bandwidth controllable receive filter coupled to the first switch and configured to selectively filter the first frequency band or the second frequency band; and
a second broadband radio frequency module including a second switch coupled to the first switch over a first signal route, a third bandwidth controllable receive filter coupled to the second switch and configured to selectively filter the first frequency band or the second frequency band, and a fourth bandwidth controllable receive filter coupled to the second switch and configured to selectively filter the first frequency band or the second frequency band.
