    Abstract: An amplification device comprising two amplifiers for receiving common input signals and outputting amplified signals respectively therefrom, and a synthesizer for synthesizing output signals of the two amplifiers and outputting them. The amplification device suppresses distortion components of the output signals of the amplifiers in a transition state. This amplification device comprises a pre-distortion compensation unit which calculates the distortion compensation component based on the output signal of the synthesizer and compensates the distortion of the input signal of the amplifiers based on the obtained distortion compensation component, and a gain control unit which reduces the gain below a normal value and attenuates the input signal below the normal level when transferring from both-operating state of the two amplifiers to either-operating state, when transferring from either-operating state to both-operating state, when either amplifier is removed, or when the removed amplifier is fitted.

    Abstract: In a slot format of a received signal, AGC gain update timings (t1 to t4) are shifted every time to disperse and reduce an influence of a noise attributable to a direct current component specific to direct conversion which is accompanied by AGC gain update. In particular, in the case where each of slots in the received signal includes an information portion (data) having a larger code correcting capability and an information portion having a smaller code correcting capability (TPC (transmission power control), TFCI (transport format combination indicator), PILOT), the AGC gain update timing is generated while being shifted in the former information portion, thereby reduce the influence of the noise. When the amount of shift of the AGC gain update timing is set to be larger than that of one symbol of the received signal, the influence of the noise accompanied by the AGC gain update is further reduced.
