PURPOSE: An apparatus for optimizing redundancy channels is provided to cover all RF paths by reducing the number of switches from 5 pieces to 3 pieces using the characteristics of the turn on/off and path changes of redundancy switches. CONSTITUTION: The first to the third redundancy switch(RS1-RS3) respectively have four paths(1-4). The first channel to the third channel(10-30), respectively connected to the first to the third redundancy switch(RS1-RS3), transfer their respective signals. The first redundancy channel(40), connected to the first redundancy switch(RS1), gets connected when the first channel(10) is in abnormal condition. The second redundancy channel(50), connected to the third redundancy switch(RS3), gets connected when the third channel(30) is in abnormal condition.
