Abstract
A radio frequency (RF) front end circuit for connecting an antenna to a transceiver having multiple operating modes is disclosed. The circuit has a first transmit input receptive to signals of a first operating mode and a second operating mode from the transceiver. There is also a second transmit input receptive to signals of a third operating mode from the transceiver. The circuit has a first power amplifier for the first and second operating modes, a second power amplifier for the first operating mode, and a third power amplifier for the second and third operating mode. A first switch network selectively interconnects the first transmit input to a one of the second and third power amplifiers.
