Abstract
According to one embodiment, a radio communication deviceincludes a variable frequency dividerthat divides a frequency of a reference clock REFCLK and outputs a frequency divided clock DCLK; a controllerthat controls a frequency dividing ratio of the variable frequency dividerso that an integral multiple of a frequency of the frequency divided clock DCLK is not included in a frequency band of a high-frequency signal that has been received from outside by radio; and a DCDC converterthat performs a switching operation in synchronization with the frequency divided clock DCLK to generate an output voltage Vout obtained by stepping down an input voltage Vin.
