Abstract

A communications apparatus includes a first transceiver, a second transceiver, a first antenna, and a second antenna. The communications apparatus further includes a front end module (FEM) coupled between the first transceiver and the first antenna, and includes an amplifier for amplifying signals received by the first antenna. The FEM directly couples the first antenna to the first transceiver when the second transceiver is transmitting signals using the second antenna, so signals received via the first antenna are not amplified by the amplifier prior to being passed to the first transceiver. Furthermore, the FEM is configured to couple the first antenna to the first transceiver via the amplifier when the second transceiver is not transmitting signals using the second antenna, so signals received via the first antenna are amplified prior to being passed to the first transceiver.
