    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.

    Abstract: In a bias circuit including a transmission line and an open stub for preventing a microwave signal from passing through, the lengths of the open stub and a transmission line between the open stub and main transmission line are near .lambda./4 but not equal to .lambda./4. A leakage signal caused by the above deviations is fed to a detector portion. In the above construction, circuit size of the bias circuit and the detector portion is minimized.

    Abstract: A FREQUENCY DISCRIMINATOR FOR PROCESSING FREQUENCY MODULATED RF SIGNALS INCLUDING A VOLTAGE LIMITER, FOUR TRANSMISSION LINES CONNECTED AT A JUNCTION, A SQUARE LAW DETECTOR AND AN AM RECEIVER. ONE TRANSMISSION LINE CONNECTS THE OUTPUT OF THE LIMITER TO THE JUNCTION, ANOTHER TRANSMISSION LINE CONNECTS THE INPUT OF THE SQUARE LAW DETECTOR TO THE JUNCTION AND THE OTHER TWO TRANSMISSION LINES FORM A SINGLE DELAY LINE WHERE EACH OF THESE TWO TRANSMISSION LINES HAS ONE END CONNECTED TO THE JUNCTION AND THE OTHER ENDS ARE CONNECTED TO EACH OTHER. IN ALTERNATIVE EMBODIMENTS THE TWO TRANSMISSION LINES ARE FORMED INTO EITHER TWO OPEN ENDED OR TWO SHORTER DELAY LINES OF EQUAL LENGTH. BECAUSE OF SIGNAL ABSORPTION AND SIGNAL CANCELLATION BY THE LIMITER, SQUARE LAW DETECTOR AND DELAY LINES A SIGAL IS APPLIED TO THE INPUT OF THE SQUARE LAW DETECTOR SUCH THAT ITS OUTPUT VOLTAGE WILL VARY LINEARLY AS A FUNCTION OF THE INPUT FREQUENCY OVER A PRE-SELECTED RANGE OF FREQUENCIES.
