PURPOSE: To provide a homodyne receiver small in size, light in weight, low in cost and low in power consumption without serious emission. CONSTITUTION: This homodyne receiver is provided with a local oscillator LO for oscillating at a frequency fLO, a mixer 11 and a reception means 12 for receiving the input signals of the frequency fRF. In the receiver, oscillation signals and the input signals are supplied to the mixer 11. The oscillation signals are supplied to a first processor 13, the first output signals of the frequency M.fLO (M is an integer) are obtained, they are supplied to a second processor 14 and the second output signals of the frequency M.fLO/N=fLO (N is the integer and N≠M) are obtained. In this case, the mixer 11 and the second processor 14 are integrated and the leakage of the signals supplied from the processor 14 to the mixer 11 is minimized.
