  • Patent number: 10090570
    Abstract: Various embodiments provide for waveguide assemblies which may be utilized in wireless communication systems. Various embodiments may allow for waveguide assemblies to be assembled using tools and methodologies that are simpler than the conventional alternatives. Some embodiments provide for a waveguide assembly that comprises a straight tubular portion configured to be shortened, using simple techniques and tools, in order to fit into a waveguide assembly. For instance, for some embodiments, the waveguide assembly may be configured such that the straight portion can be shortened, at a cross section of the portion, using a basic cutting tool, such a hacksaw. In some embodiments, the straight portion may be further configured such that regardless of whether the straight tubular portion is shortened, the waveguide assembly remains capable of coupling to flanges, which facilitate coupling the straight tubular portion to connectable assemblies, such as other waveguide assemblies, radio equipment, or antennas.

  • Patent number: 10075151
    Abstract: A solid state device chip including diodes (generating a higher frequency output through frequency multiplication of the input frequency) and a novel on-chip power combining design. Together with the on-chip power combining, the chip has increased efficiency because the diodes' anodes, being micro-fabricated simultaneously on the same patch of a GaAs wafer under identical conditions, are very well balanced. The diodes' GaAs heterostructure and the overall chip geometry are designed to be optimized for high power operation. As a result of all these features, the device can generate record-setting power having a signal frequency in the F-band and W-band (30% conversion efficiency).

  • Patent number: 10062940
    Abstract: A dielectric phase shifter comprises a cavity having an elongated receiving space, a phase shifting circuit disposed inside the receiving space, and a dielectric element slidably mounted in the receiving space and parallel with the phase shifting circuit. A rail is disposed on an inner wall of the cavity for preventing contact between the movable dielectric element and the phase shifting circuit. By providing a number of rails between the phase shifting circuit and the dielectric element, direct contact between the dielectric element and a feeding network is prevented. As a result, no additional force will be imposed on the feeding network and reliability is enhanced. Moreover, wear of the feeding network and/or dielectric element during operation of the phase shifter is eliminated.

  • Patent number: 10062939
    Abstract: A phase shifter of cavity type includes an integrally formed cavity, a feeding network disposed inside the cavity, a dielectric element disposed between the feeding network and the cavity, and at least one transmission-line transformation device. The at least one transmission-line transformation device is connected with the cavity by welding for connecting an outer conductor of a transmission cable, and for passing an inner conductor of the transmission cable into the cavity and being connected with the feeding network. Phase shifting is achieved by straight movement of the dielectric element along the longitudinal direction of the cavity. For the phase shifter of cavity type, the cavity and transmission-line transformation device are individually designed, and as a result, difficulty in design and manufacture is decreased. In addition, fasteners such as screws are not used for securing the phase shifter, thus avoiding reliability and inter-modulation problems resulted from failure of screws.
