Publication number: 20180301780Abstract: An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, ?r that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.Type: ApplicationFiled: June 14, 2018Publication date: October 18, 2018Applicant: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: MATTHEW S. TORPEY, BENJAMIN ANDREW COPLEY, JEFFREY DAVID HARTMAN, WAYNE STEPHEN MILLER

Patent number: 10074385Abstract: A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.Type: GrantFiled: May 8, 2017Date of Patent: September 11, 2018Assignee: SEAGATE TECHNOLOGY LLCInventors: Robert J.
