Abstract:
A ball grid array ceramic resonator (320) including a substrate (322) having one or more strips of conductive material (342) on opposed first and second surfaces of the substrate. One or more conductive vias (336) extend through the substrate and define termination ends in the respective substrate surfaces. In one embodiment, a plurality of conductive spheres/balls (396) defining respective ground pads are disposed over the ends of said vias terminating in said one or more strips of conductive material on said first or second surface and another conductive sphere is disposed over one of the strips of conductive material to define an RF signal input pad (398).
Abstract:
A ball grid array ceramic filter including a substrate having a ground layer of conductive material disposed over one of the surfaces thereof and a plurality of strips of conductive material on the other of the substrate surfaces defining resonators adapted to receive and pass RF signals. A plurality of vias extend through the substrate and define opposed ends terminating in the respective substrate surfaces. In one embodiment, a plurality of conductive spheres defining respective ground and RF signal input/output pads are disposed on the substrate surface with the ground layer thereon. Certain of the vias couple the resonators to the ground layer while others of the vias couple the resonators to respective spheres adapted for coupling to the respective RF signal input/output contacts on the top surface of a printed circuit board to which the filter is adapted to be direct surface mounted.
Abstract:
A voltage controlled oscillator (VCO) assembly and module incorporating a ball grid array resonator as part of the tank circuit of the voltage controlled oscillator. The VCO module preferably incorporates at least an oscillator circuit, the tank circuit, and an output buffer stage circuit all defined by a plurality of interconnected electrical/electronic components including the ball grid array resonator which are mounted to a printed circuit board. In another embodiment, the oscillator assembly also includes a phase-locked loop circuit defined at least in part by an integrated circuit mounted to the printed circuit board.
Abstract:
A confectionary composition and a method for oral care that includes Magnolia Bark Extract in combination with a surface active agent. The effectiveness of Magnolia Bark Extract in inhibiting biofilm formation in the oral cavity is increased by a synergistic combination of the Magnolia Bark Extract with a surface active agent in an oral cavity delivery agent, such as confectionary, a lozenge, a candy, and a tablet.
Abstract:
Ein Frontend-Modul zur Verwendung in einer drahtlosen Basisstation, wie einer Pikozelle, umfasst ein Gehäuse, das einen Hohlraum für einen Träger eingrenzt. Ein erster Abschnitt auf dem Träger definiert einen Signal-Sendepfad und umfasst wenigstens die folgenden diskreten elektronischen Komponenten: ein Bandpassfilter, einen Leistungsverstärker und einen Koppler. Ein zweiter Abschnitt auf dem Träger definiert einen Signal-Empfangspfad und umfasst wenigstens die folgenden diskreten elektronischen Komponenten: ein Bandpassfilter und einen Low-Noise-Verstärker. Ein Schalter auf dem Träger verbindet den ersten und den zweiten Abschnitt mit einem Antennenanschluss, und eine Wand in dem Gehäuse erstreckt sich durch einen Schlitz in dem Träger, um die Komponenten in dem ersten und dem zweiten Abschnitt zu trennen. Anschlüsse erstrecken sich durch eine Außenwand des Gehäuses und sind in Kontakt mit dem Träger.
