    Abstract: A method for manufacturing open-ended carbon nanotubes is described. The method includes steps of: providing a substrate having a catalyst layer formed thereon; placing the substrate in a reaction chamber; introducing a carbon source gas containing carbon element into the reaction chamber for growing carbon nanotubes form the catalyst layer; promptly reducing a concentration of the carbon source gas when the growth of carbon nanotubes in process, thereby ceasing the growth of the carbon nanotubes instantly; and separating the carbon nanotubes from the catalyst layer.

    Abstract: 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.

    Abstract: 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.
