ABSTRACT A mixer circuit capable of receiving two local oscilla- tion signals which is free from conversion characteristic deterioration, which suppresses leakage of local oscillation signal and which does not require a large circuit space is described. The mixer circuit has a main line for receiving an input microwave signal at its one edge and a mixer diode for mixing the input microwave signal with either of first and second local oscillation signals. One of the terminals of the mixer diode is coupled to the other edge of the mixer line and a coupling line is coupled to the other terminal of the mixer diode. The coupling line has substantially 1/4 wavelength with respect to the input microwave signal. Two distribution-coupling type bandpass filters are dis- posed along both sides of the coupling line for receiving the first and second local oscillation signals, respectively. A delivering line is coupled to the edge of the coupling line at which the mixer diode is connected for delivering an intermediate frequency signal.
