  • Patent number: 11754605
    Abstract: A series tee splitter comprises a primary electromagnetic transmission line and a secondary electromagnetic transmission line that is placed in a series path with the primary electromagnetic transmission line, wherein a load is attached to the end of the secondary electromagnetic transmission line and a network analyzer is connected to opposite ends of the primary electromagnetic transmission line to measure a load impedance. This configuration increases the high impedance measurement limit of the network analyzer normally seen for reflection measurements. The series tee splitter can be electrically small to provide broadband impedance information.
    Type: Grant

  • Patent number: 9947981
    Abstract: The various technologies presented herein relate to utilizing a sealing layer of malleable material to seal gaps, etc., at a joint between edges of a waveguide channel formed in a first plate and a surface of a clamping plate. A compression pad is included in the surface of the clamping plate and is dimensioned such that the upper surface of the pad is less than the area of the waveguide channel opening on the first plate. The sealing layer is placed between the waveguide plate and the clamping plate, and during assembly of the waveguide module, the compression pad deforms a portion of the sealing layer such that it ingresses into the waveguide channel opening. Deformation of the sealing layer results in the gaps, etc., to be filled, improving the operational integrity of the joint.

  • Patent number: 9343795
    Abstract: The various technologies presented herein relate to waveguide dividers and waveguide combiners for application in radar systems, wireless communications, etc. Waveguide dividers-combiners can be manufactured in accordance with custom dimensions, as well as in accordance with waveguide standards such that the input and output ports are of a defined dimension and have a common impedance. Various embodiments are presented which can incorporate one or more septum(s), one or more pairs of septums, an iris, an input matching region, a notch located on the input waveguide arm, waveguide arms having stepped transformer regions, etc. The various divider configurations presented herein can be utilized in high fractional bandwidth applications, e.g., a fractional bandwidth of about 30%, and RF applications in the Ka frequency band (e.g., 26.5-40 GHz).
