Abstract
A receiver device includes an antenna that receives a high frequency signal having a bandwidth, a mixer connected to the antenna and a frequency multiplier. A filter that removes a noise signal whose frequency is different from that of the local signal is provided between the local oscillator and the frequency multiplier. The filter removes the noise signal that satisfies the condition that the absolute value of the frequency difference between the center frequency of the local signal and the center frequency of the noise signal is less than the bandwidth of the high frequency signal.
