1. A wireless device comprising:
one or more antennas;
a first duplexer configured to receive a transmit signal and a first carrier-aggregated receive signal;
a second duplexer configured to receive a second carrier-aggregated receive signal, the second carrier-aggregated receive signal being in a different frequency band than the first carrier-aggregated receive signal;
an antenna switch module (ASM) coupled between the first duplexer and the second duplexer and the one or more antennas;
one or more phase-shifting components; and
at least one controller configured to selectively couple at least one phase-shifting component of the one or more phase-shifting components to the ASM based on a respective frequency of each of the transmit signal, the first carrier-aggregated receive signal, and the second carrier-aggregated receive signal.
