Abstract:
The present invention relates to a Radio Frequency Repeater to prevent oscillation with canceling a feedback interference signal between transmitting and receiving antenna with built-in transmitting and receiving antenna in wireless mobile communication repeater. A radio frequency repeater for canceling a feedback interference signal has a downlink path from a base station to a terminal and an uplink path from a terminal to a base station, and said downlink path and said uplink path is separated and combination by a duplexer.
