PROBLEM TO BE SOLVED: To realize a radio apparatus which comes in a simple composition and excels in maintainability.SOLUTION: A remote radio head 100 includes a LNA-B port 168 which receives a first transmit signal which was processed for transmission by a remote radio head 200 and then output from the remote radio head 200. Also, the remote radio head 100 includes a HYB 136 which synthesizes the first transmit signal received via the LNA-B port 168 and a second transmit signal processed for transmission by the remote radio head 100 and then outputs the synthesized signal via an antenna 172. Furthermore, the remote radio head 100 includes a HYB 148 which branches the receive signal received by the antenna 172 into a first frequency band receive signal to be used by the remote radio head 100 and a second frequency band receive signal to be used by the remote radio head 200 and then outputs the branched second frequency band receive signal to the remote radio head 200 via the LNA-B port 168. |
