Abstract:
1. A radio frequency (RF) front end circuit for connecting an antenna to a transceiver having a first operating mode, a second operating mode, and a third operating mode, comprising: a first set of transmit ports receptive to signals of the first operating mode and the second operating mode from the transceiver; a second set of transmit ports receptive to signals of the third operating mode from the transceiver; a first set of power amplifiers for the first operating mode; a second set of power amplifiers for the second and third operating modes; a first switch selectively interconnecting a one of the first set of transmit ports to a one of the first set of power amplifiers and a one of the second set of power amplifiers; a second switch selectively interconnecting a different one of the first set of transmit ports to a different one of the first set of power amplifiers and a different one of the second set of power amplifiers; a multi-position switch selectively interconnecting the antenna to a single one of the first set of power amplifiers and the second set of power amplifiers; a first set of receive ports relaying signals of the first operating mode and the second operating mode received from the antenna; and a second set of receive ports relaying signals of the third operating mode received from the antenna.
