  • Patent number: 8922424
    Abstract: A radiation type oscillator including a radiation type oscillator substrate including a microwave transistor for generating negative resistance by short-duration operation and a resonant cavity structure; a high-frequency pulse signal of an oscillation frequency/frequency bandwidth determined by negative resistance produced by the short-duration operation of the microwave transistor and the resonant cavity structure is generated as a transmitted RF signal and simultaneously radiated into space. The radiation type oscillator performs oscillating operation when a received RF signal that is a reflected wave of the transmitted RF signal from an object of detection enters the radiation type oscillator, an IF signal is acquired from an IF signal output terminal owing to homodyne mixing by the radiation type oscillator itself, and this is analyzed and processed to detect the object of detection.

  • Patent number: 8380140
    Abstract: A baseband signal processing unit changes the collector current of a transistor (20) formed by a bias control circuit (7) in accordance with a baseband transmission signal input from a baseband signal input terminal (18), changing the drain bias of a high-frequency transistor (1) to realize frequency modulation by changing the oscillation frequency, and the radiation wave thereof forms a transmit RF signal, whereby the transmission operation is performed. On the other hand, the oscillation signal is synchronized with a frequency modulated RF signal that arrives from outside, the change in frequency caused by the frequency modulation is generated as a change in the drain bias of the high-frequency transistor (1), and reception operation is performed by taking out that change as a voltage amplitude change from the baseband signal output terminal (14). As a result, it is possible to provide a microwave/millimeter wave communication apparatus that is simple in structure, low cost, and low power consumption.

  • Patent number: 7979101
    Abstract: It is possible to improve the negative resistance characteristic that can be expected when an SNS (superconductor-normal conductor-superconductor) structure is used as a structure unit for series connection. On the top of a first superconducting electrode, a second superconducting electrode is superimposed so as to sandwich an insulation film between the first and second superconducting electrodes, with parts of cross sections of the second superconducting electrode and insulation film placed on the top. A normal superconducting line electrically connects the first and second superconducting electrodes passing along the cross section of the insulation film, thereby constituting a structure unit having a single weak link. A plurality of such structure units connected in series are prepared. At the both ends of the series the first or second superconducting electrode is an element connected to a leading line.
