    摘要： A method according to one embodiment identifying the frequency range of at least one active channel of at least one wireless communication RF band; identifying the frequency range of at least one clock harmonic; identifying an overlap, in whole or in part, between the frequency range of the at least one active channel and the frequency range of the at least one clock harmonic; and shifting a fundamental frequency of the at least one clock to shift the frequency range of the at least one clock harmonic out of, at least in part, the frequency range of the at least one active channel. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

    摘要： A first apparatus includes a semiconductor device and a heatsink thermally coupled to the semiconductor device. The heatsink is located and formed to screen the device from external electromagnetic radiation or to contain radiation produced by the device. A second apparatus includes a semiconductor device, a heatsink thermally coupled to the semiconductor device, and a grounding structure having a capacitive coupling to the heatsink.

    摘要： A substrate for reducing electromagnetic emissions is provided. The substrate may include a plurality of ground layers, signal layers and power layers. All of the layers other than the ground layer are provided with a ground ring that may extend around the perimeter of the layer. The ground rings are electrically coupled together by ground stitching or vias that are randomly spaced. The random spacing of the ground stitching is based on the operating frequencies of the integrated circuit devices mounted on the substrate. Additional shielding may be provided by providing a cover assembly made of any conductive material that is coupled to the exposed ground rings on the uppermost and lowermost surfaces of the substrate. The cover assembly is coupled to the exposed ground rings in a randomized pattern. The device provides a virtual electrical ground cage in which the internal signal layers are totally enclosed, thereby reducing electromagnetic emissions.

    摘要： Embodiments of an optically transparent antenna are generally described herein. In some embodiments, the optically transparent antenna may comprise a plurality of electrically-isolated conductive patches arranged on a non-conductive surface. A combination of a size of the conductive patches and a spacing between the conductive patches is less than a human visual acuity for a predetermined viewing distance so that the patches are not be visible or perceptible to a human. In some embodiments, optically transparent antenna may serve as one or more antennas on a mobile platform.
