PROBLEM TO BE SOLVED: To appropriately control a power level of carriers of an individual channel. SOLUTION: A multiplex channel converter 110 for generating a plurality of analog reference signals in correspondence to a plurality of digital input signals generates an analog multiplex carrier signal, to sample a multiplex carrier signal. The multiplex carrier signal expresses an amplification obtained by totalizing the digital input signals. A correlative power detector 60 is connected to the multiplex channel converter, to generate a digital general power control signal based on the analog reference signals and analog sample multiplex carrier signals. A feedback conversion module 120 is connected to the multiplex channel converter and correlative power detector, to control the amplification of the digital input signal in each channel based on the digital general power control signal.
