摘要： A radio reception device for receiving both terrestrial and satellite digital broadcasting. The device includes a reception device for a first radio communication method and a reception device for a second radio communication method. The reception device for a first radio communication method includes a first reception unit which receives and amplifies a first input frequency signal, a Local Oscillation (LO) signal generation unit which generates an LO frequency signal, a first mixing unit which outputs a frequency down-converted signal, and a signal processing unit which receives the signal output from the first mixing unit and performing signal processing. The reception device for a second radio communication method includes a second reception unit which receives and amplifies a second input frequency signal, a frequency divider, and a second mixing unit which outputs a frequency down-converted signal to the signal processing unit.
