<p>PROBLEM TO BE SOLVED: To provide a receiving device having interference wave resistance characteristics of a single conversion method and reception sensitivity characteristics and power-saving characteristics of a double conversion method, and capable of properly switching the interference wave resistance characteristics and the power-saving characteristics even when a discontinuous input signal is received.SOLUTION: A receiving device comprises: a first mixer 5 which mixes an input signal and a first frequency signal, and then outputs a first intermediate frequency signal; a second mixer 8 which mixes the first intermediate frequency signal output from the first mixer 5 and a second frequency signal, and then outputs a second intermediate frequency signal; and a demodulation unit which demodulates the second intermediate frequency signal output from the second mixer 8. The receiving device further comprises: a bypass 30 which inputs an input signal to the second mixer 8, bypassing the first mixer 5; and a change-over switch 3 which switches an input destination of the input signal to the first mixer 5 or the second mixer 8.</p> |
