ミキサ。 A waveguide divided at the center perpendicular to the long side of the rectangular waveguide, a dielectric substrate sandwiched between the two divided rectangular waveguides, and a signal terminal in the rectangular waveguide. In addition, in a dielectric substrate structured to be inserted into a rectangular waveguide, a microwave line converted to a slot line and a coplanar line and a microwave line converted to a slot line and a coplanar line and a local terminal can be connected from the signal terminal side of the rectangular waveguide. A microwave line converted from a slot line to a coplanar line, a beam-lead mixer diode attached to the coplanar line, and a resonator behind the beam-lead mixer diode that totally reflects the microwave input from the signal terminal. It is installed on the back side of the coplanar line about 1/4 wavelength behind the tube wavelength, and it is installed in front of the installation position of the beam lead type mixer diode or on the back side of the slot line or coplanar line between it and the resonator. A mixer characterized by having a matching stub formed by a microtrip line.
