AMPLIFICATION DEVICE AND COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an amplification device that has an improved amplification characteristic.SOLUTION: An amplification device 1 includes a decomposition section 10, 21, 22, two amplifiers 31, 32, a combiner 50 and a control section 10. The decomposition section decomposes an input signal into two signals different in phase. The two amplifiers amplify the two signals decomposed, respectively. The combiner combines outputs of the amplifiers. The control section controls at least one of waveform information of at least one of the two signals and operating states of the two amplifiers such that an output characteristic of the combiner matches a desired characteristic.
