PURPOSE: A combi-tuner for ground and satellite broadcasting is provided to receive both of ground wave and satellite wave. CONSTITUTION: A combi-tuner for ground and satellite broadcasting includes a satellite frequency output unit for receiving satellite wave to output a predetermined frequency, the first switch(115) for selectively outputting a radio-frequency signal inputted from an antenna(ANT1) or the radio-frequency signal output from the satellite frequency output unit to an AGC(101), and the second switch(116) for selectively providing the second IF frequencies output from a mixer. The tuner further includes the first low pass filter(117) for passing only the frequency of 10MHz among the second IF frequencies output from the second switch, and the second low pass filter for passing only the frequencies of 10-45MHz among the second IF frequencies output from the second switch.
