Patent number: 7915981Abstract: Coaxial-to-microstrip transitions may include a microstrip line and coaxial-line assembly. The microstrip line includes a first dielectric having an aperture, a conductive strip disposed on one primary face of the first dielectric, and a ground plane disposed on the opposite primary face of the first dielectric. The coaxial-line assembly includes an outer conductor and an inner conductor. In some examples, the ground plane extends between the outer conductor and the inner conductor on a first side of the coaxial-line assembly proximate the conductive strip and an aperture cross section extends beyond the outer conductor on a second side of the coaxial-line assembly distal the conductive strip. In some examples, the ground plane has a non-circular aperture. In some examples, the outer conductor encloses an area that is less than an area of the aperture. In some examples, the enclosed area has a width that is less than a corresponding width of the first aperture.Type: GrantFiled: May 27, 2010Date of Patent: March 29, 2011Assignee: Microsemi CorporationInventors: David K Snodgrass, Thomas M Gaudette, Mark V Faulkner, Thomas G Flack, Thomas E Halterman, Mario Pinamonti La Marche, Edward B Anderson

Patent number: 7813145Abstract: A cover assembly may be mounted on a substrate. The cover assembly may have an interior surface spaced from the substrate and may bound a hollow chamber over a circuit assembly. The hollow chamber may be filled with a fluid, such as a gas or a liquid. The cover assembly may also have an edge extending along the substrate around the circuit assembly and may include a dielectric cover, an electromagnetic shield, a conductive assembly, a resistive layer, and an aperture with a gas-permeable membrane. The electromagnetic shield. The dielectric cover may substantially enclose the hollow chamber bounded by the cover assembly. The electromagnetic shield may be attached to the dielectric cover and also substantially enclose the hollow chamber. The conductive assembly may extend along and may be electrically isolated from the electromagnetic shield. The conductive assembly may be conductively coupled to the circuit assembly.Type: GrantFiled: March 27, 2007Date of Patent: October 12, 2010Assignee: Endwave CorporationInventors: Edward B.

Patent number: 7588966Abstract: A circuit structure may be formed in a substrate having a face and an open trench, where one or more chips are to be mounted. At least one bridge may extend across an intermediate portion of the trench, and optionally, may divide the trench into sections. A conductive adhesive layer may be applied to the substrate face and, if included, the bridge. One or more circuit chips may be mounted on the adhesive layer, with at least one edge of one circuit chip adjacent to the trench. Alternatively or additionally, an adhesive layer may be applied to a base of a chip and then mounted to the substrate face, in like fashion. The trench may accommodate excess adhesive flowing out from under the one or more chips, while the bridge retains the adhesive across the width of the trench. If the adhesive is conductive, this provides continuity of the conductive layer on the face of the substrate across the trench.Type: GrantFiled: March 4, 2008Date of Patent: September 15, 2009Assignee: Endwave CorporationInventors: Edward B.

Patent number: 7411279Abstract: An example of a circuit structure may include a first dielectric layer having first and second surfaces, and a channel extending at least partially between the first and second surfaces and along a length of the first dielectric layer. First and second conductive layers may be disposed on respective portions of the first and second surfaces. A first conductor, having an end, may be disposed on a surface of the first dielectric layer, including at least a first portion extending around at least a portion of the conductor end. The second conductive layer may line the channel extending around a portion of the conductor end. Some examples may include a stripline having a second conductor connected to the first conductor. Some examples may include a cover having a wall positioned on the first dielectric over the second conductor.Type: GrantFiled: June 30, 2004Date of Patent: August 12, 2008Assignee: Endwave CorporationInventors: Edward B.

Patent number: 7145414Abstract: A circuit structure may include first and second transmission lines, each with a center conductor extending along or between one or more spaced-apart conducting surfaces. A conducting surface, such as a ground, reference, or signal-return plane, of the first transmission line may have an orientation that is transverse to the orientation of a conducting surface of the second transmission line. Each of the conducting surfaces of the first transmission line may contact one or more of the conducting surfaces of the second transmission line. In some examples, one or both of the transmission lines are slablines, and in some examples, the contacting edges or edges adjacent the contacting edges of the respective conductive surfaces are curved.Type: GrantFiled: June 30, 2004Date of Patent: December 5, 2006Assignee: Endwave CorporationInventors: Douglas Seiji Okamoto, Anthony C.

Publication number: 20040004522Abstract: The disclosed example of an N-way RF divider has a first conductor that directs RF energy through a body to a common node of a planar conductive pattern of equiangularly spaced, radially extending arms of equal length. Secondary conductors extend orthogonally to the planar pattern through corresponding passages from the ends of the radial arms. The secondary conductors may extend parallel to and circumferentially spaced from the first conductor. Resistors may connect adjacent ends of the secondary conductors opposite from the planar conductive pattern.Type: ApplicationFiled: July 2, 2003Publication date: January 8, 2004Inventors: Anthony C.
