<P>PROBLEM TO BE SOLVED: To obtain a high-frequency receiving unit having a good reception sensitivity. <P>SOLUTION: A tuner unit 103 includes a mixer 113, an output terminal 117 to which a signal output from the mixer 113 is supplied, and an oscillator 121 input into the other input terminal of the mixer 113 than one into which a high-frequency signal is input. A tuner unit 105 includes a mixer 137, an output terminal 141 to which a signal output from the mixer 137 is supplied, and an oscillator 145 input into the other input terminal of the mixer 137 than one into which a high-frequency signal is input. Between the oscillator 121 and the other input terminal of the mixer 113, a frequency divider 119 is connected that receives an input signal and generates an output signal having a frequency of one-Nth of that of the input signal (N is an integer of 2 or above). <P>COPYRIGHT: (C)2010,JPO&INPIT |
