ABSTRACT:
A diode circuit in a dielectric waveguide device designed to improve the facility with which a circuit substrate is mounted in the dielectric waveguide, to make matching between a dielectric waveguide and a diode easier, and to reduce conversion losses, and a detector and a mixer using such a diode circuit. A conductor pattern is disposed so as to intersect a pair of dielectric strips substantially perpendicularly to the same, and two filter circuits are formed in the dielectric pattern on opposite sides of the dielectric strips, thereby forming a resonance circuit. A diode is mounted in the resonance circuit in series with the conductor pattern.
