  • Publication number: 20180233269
    Abstract: A transmission line impedance transformer including at least two different dielectric media having different dielectric properties, each of the dielectric media being configured to taper in thickness along the length of the impedance transformer in an inverse relationship with respect to each other so as to form a combined dielectric medium having an effective dielectric property that is graded along the transmission path. The two or more dielectric media may be disposed between two conductors to provide an impedance transformer in which a characteristic impedance of the transmission line varies along its length in response to the gradation of the effective dielectric property of the combined dielectric medium.

  • Publication number: 20170105311
    Abstract: An electronic module, and method for making same, includes free-formed, self-supported interconnect pillars that electrically connect cover electronic components disposed on a cover substrate with base electronic components disposed on a base substrate. The free-formed, self-supported interconnect pillars may extend vertically in a straight path between the cover electronic components and the base electronic components. The free-formed, self-supported interconnect pillars may be formed from an electrically conductive filament provided by an additive manufacturing process. By free-forming the self-supported interconnect pillars directly on the electronic components, the flexibility of electronic module design may be enhanced, while reducing the complexity and cost to manufacture such electronic modules.

  • Patent number: 7002441
    Abstract: A micro-electro-mechanical (MEMS) switch (10, 110) has an electrode (22, 122) covered by a dielectric layer (23, 123), and has a flexible conductive membrane (31, 131) which moves between positions spaced from and engaging the dielectric layer. At least one of the membrane and dielectric layer has a textured surface (138) that engages the other thereof in the actuated position. The textured surface reduces the area of physical contact through which electric charge from the membrane can tunnel into and become trapped within the dielectric layer. This reduces the amount of trapped charge that could act to latch the membrane in its actuated position, which in turn effects a significant increase in the operational lifetime of the switch.
