Abstract
A microwave detector includes a horn antenna and cavity formed by covering a metallic film of a printed substrate with an opened bottom microwave circuit component, and further includes a mixer diode which is positioned at the feeding point of the horn antenna and sandwiched between the microwave circuit component and the printed substrate, the mixer diode including a mixer diode substrate having a first protruding portion at a first end of the mixer diode substrate and a second protruding portion at a second end of the mixer diode substrate, separate anode and cathode electrode patterns formed on a surface of the substrate which includes the protruding portions, and a beam-lead-type or flip-chip-type diode which is mounted to a surface of the mixer diode substrate near the center thereof, the beam-lead-type or flip-chip-type diode having an anode and a cathode which are surface mounted to the anode and cathode electrode patterns to form electrically conducting pathways therewith, wherein the first and second protruding portions are directly or indirectly connected respectively to the microwave circuit component and the printed substrate.
