  • Switch Circuit
    Publication number: 20090027138
    Abstract: A switch circuit including: a plurality of MEMS switches connected in parallel or in series, which have different drive voltages; and a single voltage supply for driving the plurality of MEMS switches by the plurality of drive voltages, is used for a microwave circuit or an antenna circuit, to vary a configuration of the microwave circuit or the antenna circuit based on the drive voltage value. That is, the configuration of the microwave circuit or the antenna circuit can be varied based on the drive voltage value by using the switch circuit including the MEMS switches having the different drive voltages for the microwave circuit or the antenna circuit.

  • Transition circuit
    Patent number: 7439831
    Abstract: A transition circuit includes: a waveguide having a notched portion formed by cutting away a portion of the tube wall of the waveguide from the end portion of the waveguide; a dielectric substrate in which a portion extending outside the waveguide through the notched portion of the waveguide is formed; a plurality of polygonal conductor patterns formed regularly disposed on the dielectric substrate; a ground conductor formed on the dielectric substrate; through holes electrically connecting this ground conductor and each of the conductor patterns; an open stub formed on the dielectric substrate; and the conductor of a microwave transmission line, which is formed on the portion of the dielectric substrate, extending outside the waveguide, and which is electrically connected to the open stub.
