Abstract
A multi-band, multi-mode radio frequency (RF) front-end module is capable of operating in widely different frequency bands, including at least one of the following frequency ranges: 700 megahertz (MHz), 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2.1 gigahertz (GHz) or 2.4 GHz. The multi-band, multi-mode RF front-end module is also capable of operating according to different mobile communication standards, including at least one of the following standards: GSM, WCDMA, EDGE or LTE. The multi-band, multi-mode RF front-end module includes a plurality of broadband amplifiers, a plurality of transmit (TX) paths selectively connectible to respective broadband power amplifiers; and a plurality of switches. One switch is selectively operable to couple one plurality of TX paths to one broadband power amplifier operable to amplify TX signals within one range of frequencies. A second switch is selectively operable to couple a second plurality of TX paths to a second broadband power amplifier operable to amplify TX signals within a second range of frequencies.
