US Classification:

343771, 343772, 343786, 333135

Abstract:

A dual band antenna feed is made with an embedded waveguide structure to enable combining of Ka and Ku band signals without the need for an additional cavity-type filter. The antenna feed includes a Ka and Ku band interface section ( ) with two Ka band vertical polarization waveguide sections ( ) and ( ), and a single Ku band waveguide section ( ) which carries both vertical and horizontal polarization Ku band signals. The opposing walls ( ) of the Ku band waveguide ( ) carrying the vertical polarization Ku band signals are transitioned to step down from an input section ( ) to successively smaller dimensioned sections ( ), and then to step back up in successively larger dimensioned sections ( ) to an output section ( ). The two Ka band sections ( ) are fed into openings in Ku band section. ( ), on opposite sides of the opening for the Ku band transition section ( ).

International Classification:

G11C007/00

US Classification:

365201, 365154

Abstract:

A method for testing a semiconductor wafer. An array of probes is coupled to the semiconductor wafer. Then a voltage difference is applied across a plurality of adjacent metal line pairs (e. g. , wordline and/or bitline pairs) of one or more SRAM arrays of at least one die. Application of the voltage difference induces failure of metal stringers or defects between the adjacent lines. Additionally, the voltage can be applied across respective pairs of substantially all parallel metal lines of the one or more SRAM arrays of more that one die of the semiconductor wafer.

International Classification:

H01Q 13/10

US Classification:

343771

Abstract:

A method for manufacturing an extruded slot antenna array includes extruding a slot antenna body, the slot antenna including a first major surface, a second major surface, first and second external side walls, and one or more longitudinally extending internal waveguide walls disposed between the first and second major surfaces. Each of the internal waveguide walls forms a respective two or more open-ended waveguides, each open-ended waveguide having a first open end and a second open end. An array of slots is cut on the first major surface of the slot antenna body, the array of slots being arranged in a plurality of rows, one row of slots being formed along a longitudinal line of a respective open-ended waveguide. Next, a row of slots are subsequently cut on the second major surface of the extruded slot antenna body, the row of slots formed substantially perpendicularly to the longitudinal axis of the open-ended waveguides, one of the slots being formed on each of the open-ended waveguides. Next, end caps are attached to the first and second open-ends of each of the open-ended waveguides.
