| Zusammenfassung: | A signal receiving device is provided which can prevent the imbalance occurring between in-phase and quadrature signals. A polarity of a local oscillator output signal to be outputted from a local oscillator 13 is switched by a polarity switching unit 14 in a time division way. Each of signals outputted from the polarity switching unit 14 is frequency divided by a frequency divider 16. The frequency-divided local oscillation signal is supplied to a mixer 34. Frequency conversion of a receiving signal is performed by the mixer 34 which receives the signal and local oscillation signal to demodulate received data. |
