1. A radio frequency circuit comprising:
at least one transmit amplifier configured to amplify signals of at least a first frequency band and a second frequency band, and at least one receive amplifier configured to amplify signals within at least the first frequency band and the second frequency band;
a plurality of filters including a first filter configured to pass the second frequency band and block the first frequency band and a second filter configured to pass both the first frequency band and the second frequency band;
an antenna switch coupled between the plurality of filters and an antenna; and
a plurality of switches coupled between the at least one transmit amplifier, the at least one receive amplifier, and the plurality of filters, the radio frequency circuit configured in a non-concurrent mode to control the antenna switch to connect the antenna to the second filter and not the first filter, and configured in a concurrent mode to connect the antenna to both the first filter and the second filter.
