1. Communication circuitry, comprising:
a first radio frequency (RF) chain configured to output a first transmission signal in a first frequency band through a first antenna or receive a first reception signal in the first frequency band through the first antenna;
a second RF chain configured to output a second transmission signal in a second frequency band through a second antenna or receive a second reception signal in the second frequency band through the second antenna;
a first reception chain configured to receive a first signal in the first frequency band, which is received through the second antenna;
a second reception chain configured to receive a second signal in the second frequency band, which is received through the first antenna;
a first multiplexer configured to separate the first transmission signal in the first frequency band, the first reception signal in the first frequency band, and the second reception signal in the second frequency band;
a second multiplexer configured to separate the second transmission signal in the second frequency band, the first reception signal in the first frequency band, and the second reception signal in the second frequency band; and
a switch configured to connect the first RF chain and the second reception chain to the first antenna and connect the second RF chain and the first reception chain to the second antenna,
wherein the switch comprises:
a first terminal connected to the first antenna;
a second terminal connected to the second antenna;
a third terminal connected to the first RF chain and the second reception chain; and
a fourth terminal connected to the second RF chain and the first reception chain,
wherein the first RF chain and the second reception chain are connected to the third terminal through the first multiplexer, and
wherein the second RF chain and the first reception chain are connected to the fourth terminal through the second multiplexer.
