This document discloses a base station apparatus, comprising: a first radio frequency signal line designed to convey a first radio frequency transmission signal and a first radio frequency reception signal between a first antenna port and a signal processing circuitry of the base station apparatus; a second radio frequency signal line designed to convey a second radio frequency transmission signal and a second radio frequency reception signal between a second antenna port and the signal processing circuitry of the base station apparatus; a power amplifier coupled to the first radio frequency signal line to employ the first radio frequency signal line only for transmission; and a duplexer coupled to the first radio frequency signal line and the second radio frequency signal line and configured to couple the first radio frequency signal line and the second radio frequency signal line to the same antenna. |
