PROBLEM TO BE SOLVED: To obtain an amplification apparatus capable of avoiding a state where a reception quality is deteriorated or reception is disabled if a high frequency amplifier or a receiver is affected by an interference wave caused by a distortion. SOLUTION: An amplification apparatus comprises a first amplifier 39a to which a first branch transmission line branching an AC signal transmission line for transmitting an AC signal is connected and in which the AC signal inputted from the first branch transmission line is outputted with an amplification value corresponding to a first control signal; a second amplifier 39b to which a second branch transmission line branching the AC signal transmission line is connected and in which the AC signal inputted from the second branch transmission line is outputted with an amplification value corresponding to a second control signal; and an output synthesizing section 310 for outputting the sum of the amplification value of the first amplifier and the amplification value of the second amplifier. The first control signal and the second control signal control an amplification value of any one of the first amplifier and the second amplifier to be reduced so as not to affect the other amplification value.
