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, 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 power amplifier having an output coupled to the first switch through the first bandwidth controllable transmit filter; and
a radio frequency power amplifier module configured to transmit in a third frequency band, the first broadband radio frequency module and the radio frequency power amplifier module configured to operate with a shared power amplifier supply voltage.
