  • Waveguide to microstrip line N-port power splitter/combiner
    Patent number: 10177726
    Abstract: A power splitting (or combining) arrangement includes a waveguide having a plurality of output (or input) ports and an input (or output) port configured to receive (or transmit) electromagnetic waves having a frequency in a designated frequency band. Each output (or input) port is configured to electrically couple with an input (or output) terminal of a corresponding one of a plurality of active devices. Each output (or input) port has a respective output impedance associated with the frequency band. The power splitting (or combining) arrangement is configured such that the respective output (or input) impedance of each output (or input) port substantially matches an input (or output) impedance of the corresponding one of the plurality of active devices.

  • Dielectric resonator filter and multiplexer having a common wall with a centrally located coupling iris and a larger peripheral aperture adjustable by a tuning screw
    Patent number: 9705171
    Abstract: A radio frequency (RF) dielectric resonator filter includes at least a first cavity and a second cavity, each cavity being loaded with a dielectric resonator. The first cavity is separated from the second cavity by a common wall, the common wall including a first and second aperture that couple an electromagnetic field between the first cavity and the second cavity. A first externally adjustable tuning screw extends from the second aperture, a portion of the tuning screw being external to the filter. The first aperture is an iris disposed in a central portion of the wall and the second aperture is disposed proximate to a perimeter of the wall. The second aperture has an effective area that is adjustable by the first externally adjustable tuning screw.
