Abstract
According to the present disclosure, there is provided a signal generation apparatus including: a base band module (11); a DA converter that converts digital base band signals into modulation signals corresponding to a plurality of cells; an RF converter (20) to which the modulation signals corresponding to the plurality of cells are input, and which outputs an RF signal obtained by frequency-converting the modulation signal; and an RF converter control unit (31), in which the RF converter control unit controls the base band module to reduce a power value of a digital base band signal corresponding to a predetermined cell, among the digital base band signals corresponding to the plurality of cells in the base band module so that an input level of the modulation signal input to the RF converter is equal to or lower than an input limit value of the RF converter.
