A redundancy switch apparatus is provided to perform a stable flow of a signal in a system by transmitting a signal of an abnormal amplifier to a normal amplifier. In a redundancy switch apparatus, first and second switches(410,420) switch a signal to two routes. The signal is inputted from first and second input ports. A combiner(460) is connected to one of the two routes of the first and second switches(410,420) respectively. The combiner(460) adjusts power of the two inputted signals to a half of the power and combines the power of the two signals. A third switch(430) switches the signal output from the combiner(460) to the two routes. A forth switch(440) switches the other route of the two routes of the first switch(410) and one route of the third switch(430) to output to the first output port. A fifth switch(450) switches the other route of the two routes of the second switch(420) and the other route of the third switch(430) to output to the second output port. |
