The present invention relates to a satellite broadcast receiver. The satellite broadcast receiver according to the present invention comprises: first and second receivers to receive signals from a satellite; a oscillation frequency varying unit to vary a frequency oscillated from an oscillator to be tuned with a desired channel; and a mixer to input a satellite signal received at least either the first receiver or the second receiver and an output signal from the oscillation frequency varying unit and to adjust a frequency of the satellite signal so that the frequency of the satellite signal can be the same as an oscillation frequency of the oscillation frequency varying unit. According to the present invention, a dual satellite receiver having an internal automatic gain controller (AGC) structure is integrated to be a single chip, thereby miniaturizing a size of the chip due to sharable lots of blocks, simplifying an application, and reducing power consumption.
