Abstract
A communication apparatus includes a first duplexer, a second duplexer, and a switch. In a first switch position, a first output end of the switch is connected to a first branch at which the first duplexer is located. In a second switch position, a second output end of the switch is connected to a second branch at which the second duplexer is located. A transmit filter of the first duplexer corresponds to a first uplink band. A receive filter of the first duplexer corresponds to a first downlink band. A bandwidth of the first downlink band is greater than a bandwidth of the first uplink band. A transmit filter of the second duplexer corresponds to a second uplink band. A receive filter of the second duplexer corresponds to a second downlink band. A bandwidth of the second downlink band is greater than a bandwidth of the second uplink band.
