Abstract
A communications apparatus includes a first and second transceiver, and a first and 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, and a bypass line. The FEM is configured to couple the first antenna to the first transceiver via the bypass line when the second transceiver is active and transmitting signals using the second antenna such that a signal received via the first antenna is 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 such that a signal received via the first antenna is amplified.
