Radio-frequency receiver contains a plurality of oscillation circuits that generates an oscillation frequency higher than that of digital broadcasting signals, selective switching circuit that selects two out of the oscillation circuits for signal output, and first and second frequency-divider sections that provide the signals with frequency dividing. The receiver receives two channels in the digital broadcasting signals at the same time by selection of oscillation signals and frequency dividing in the first and the second frequency-divider sections under the control of PLL controller.
