<P>PROBLEM TO BE SOLVED: To provide an electronic device which can prevent deterioration in reception performance caused by in-band spurious components arising from higher harmonic waves whose frequencies are integral multiples of a clock frequency. Ž<P>SOLUTION: F<SB>LO</SB>=N×f<SB>clk</SB>(1); and (N-1)×f<SB>clk</SB><fD1<N×f<SB>clk</SB><fD2<(N+1)×f<SB>clk</SB>(2) are established, where: f<SB>clk</SB>represents a clock frequency; f<SB>LO</SB>represents a frequency of a local oscillator signal; N represents an integer; fD1 represents a lower limit frequency of a received signal; and fD2 represents an upper limit frequency of the received signal. Even if harmonic components whose frequencies are integral multiples of the clock frequency f<SB>clk</SB>are mixed as spurious components into a path for a target signal, they do not fall within the band of the target wave after frequency conversion by a mixer. Thus, it is possible to prevent deterioration in reception performance caused by in-band spurious components arising from higher harmonic waves whose frequencies are integral multiples of a clock frequency.
