    摘要: A multiplexer, such as a diplexer, is delineated. The multiplexer may be employed in a communications system that may communicate in multiple frequency bands within a predefined range of frequencies, e.g., 2400 MHz-4900 MHz. The communications system may operate in a network, such as a wireless local area network, without significant interference from signals used by a cellular/mobile telephone system. The multiplexer may include multiple channels with bandpass filters that may be formed with lumped inductors and lumped capacitors. In at least one of the channels, the bandpass filter may be formed by combining at least one lowpass filter with at least one highpass filter.

    摘要: A wide-band balun device includes a first metallization deposited over a substrate and oriented in a first coil. The first coil extends horizontally across the substrate while maintaining a substantially flat vertical profile. A second metallization is deposited over the substrate and oriented in a second coil. The second coil is magnetically coupled to the first coil and a portion of the second coil oriented interiorly of the first coil. A third metallization is deposited over the substrate and oriented in a third coil. The third coil is magnetically coupled to the first and second coils. A first portion of the third coil is oriented interiorly of the second coil. The third coil has a balanced port connected to the third coil between secondhand third portions of the third coil.

    摘要: A device (20) for manufacturing a carbon nanotube array (10) includes a reaction chamber (220), a gas introducing tube (228), and a quartz boat (240). The reaction chamber includes a first gas inlet (222), a second gas inlet (224), and a gas outlet (226). The first gas inlet is configured for introducing a reaction gas, and the second gas inlet is configured for introducing a disturbance gas. The quartz boat is disposed in the reaction chamber. The quartz boat is used to carry a substrate (12) from/upon which the carbon nanotube array grows. The gas introducing tube is connected to the second gas inlet and to the quartz boat. The gas introducing tube is used to transport the disturbance gas introduced from the second gas inlet to the quartz boat to disturb/interrupt nanotube growth.

    摘要: Methods are described for synthesizing stoichiometric LiBC and hole doped Li1-xBC (lithium borocarbide) according to heating processes, such as by both an arc-melting method and a sealed tantalum ampoule method. The arc-melting method requires forming a pellet of uniformly-mixed elemental lithium, boron, and graphite and subjecting it to an arc-melt process sufficient to trigger a self-propagating exothermic reaction. Alternatively, the titanium ampoule method requires sealing uniformly-mixed elemental lithium, boron, and graphite (Li—B—C) in a tantalum ampoule; and heating under sufficient temperature for a sufficient period of time. Hole-doped Li1-xBC (0≦x≦0.37) can then be produced, such as through vacuum de-intercalation from the LiBC. According to the present invention, the hexagonal crystal lattice remains largely intact, with only slight decreases in lattice parameters upon hole-doping. The samples are intrinsically diamagnetic and are semiconducting in the 2 K to 300 K range studied.

    摘要: An access point receives uplink transmissions from client stations using directional antenna beams. The directional antenna beams are generated by an antenna array. The different directional antenna beams are assigned beam identification numbers, and a preferred antenna beam is selected for each client station. The client stations in the different antenna beam regions initiate their uplink transmissions using assigned backoff slots within the contention window. The access point selects the preferred directional antenna beam corresponding to the directional antenna beams assigned to the backoff slots.
