    Abstract: An apparatus for conveying an electrical signal includes: a conductive pathway having a conductive material. The conductive material has a first edge and a second edge and is configured to convey the electrical signal. The apparatus also includes a resistive material in contact with at least a portion of the conductive pathway, covering an edge of the conductive pathway, and extending beyond the edge. The resistive material has a conductivity less than the conductivity of the conductive material.

    Abstract: A waveguide mechanical phase adjuster includes at least one pair of dielectric rods nominally spaced ¼ wavelength apart and inserted through a corresponding pair of holes in the wall of a waveguide. The holes are dimensioned so that they are in “cutoff” at the top end of the spectral band. An adjustment mechanism sets the insertion depth of the rods, which determines the amount of dielectric loading and, in turn, the insertion phase. Changing the insertion depth changes the dielectric loading, hence the insertion phase. The ¼ wavelength spacing of the rods serves to cancel reflected energy. Additional pairs of dielectric rods can be similarly configured and actuated to increase the range over which the insertion phase can be adjusted. The waveguide mechanical phase adjuster is well adapted for use with power combiners to maintain tight phase coherence between channels.

    Abstract: An encapsulation for electronics is provided. The encapsulation includes a circuit card assembly (CCA) on which a component of the electronics is operably disposed, a compliant thermal buffer coating (TBC), thermoset material and high-performance thermoplastic materials. The compliant TBC is layered over the component and a first area of the CCA, which extends about a periphery of the component. The thermoset material is cast over the compliant TBC and a second area of the CCA, which extends about a periphery of the compliant TBC. The high-performance thermoplastic material is injection molded over the thermoset material and a third area of the CCA, which extends about a periphery of the thermoset material.

    Abstract: In one aspect, a Y-splitter includes a first arm having a first port, a second arm having a second port, a third arm having a third port, a fourth arm having a fourth port and a Y-split portion having a first end coupled to the first arm, a second end coupled to the second arm, a third end coupled to the third arm and a fourth end coupled to the fourth arm. The Y-split portion splits a signal from a first signal path from the first port into a second signal on a second signal path and a third signal on a third signal path. A first angle between the second signal path and the first signal path is greater than 90 degrees and a second angle between the third signal path and the first signal path is greater than 90 degrees.
