Abstract: Separation of sub-bands of communications signals to reduce interference in distributed antenna systems (DASs) is disclosed. A sub-band separation circuit coupled to a plurality of antennas is configured to distribute and receive and transmit a pair of downlink and uplink sub-band signals.

In order to isolate the downlink communications signals from the uplink communications path in the remote unit, the isolation circuit includes a plurality of sub-band isolation circuits. Each sub-band isolation circuit is configured to isolate at least one sub-band of the downlink communications signal to generate a downlink sub-band signal that has a desired frequency separation or gap with uplink communication signals received at the duplexed port.

Abstract: A process is disclosed for preparing a resin-linear organosiloxane block copolymer by reacting a linear organosiloxane and an organosiloxane resin to form a resin-linear organosiloxane block copolymer. The resulting resin-linear organosiloxane block copolymer is then crosslinked to increase the average molecular weight of the resin-linear organosiloxane block copolymer. The resin-linear organosiloxanes block copolymers prepared by the disclosed process may provide solid, optically clear compositions which may be considered as “reprocessable.

Abstract: Interconnect cables utilize bend-insensitive fibers and relatively large free space areas in the cable jackets to reduce bend-induced delta attenuation. Tensile yarns can be included as strain-relief components, but can be relatively loosely packed in order to inhibit bend-induced attenuation.
Abstract: Embodiments disclosed include variable amplitude signal generators for generating a sinusoidal signal having limited direct current (DC) offset variation and related devices and methods. Instead of employing a single pulse width modulation (PWM) signal to generate a sinusoidal signal, in one embodiment, a circuit is provided that generates two PWM signals. The first PWM signal is a high-to-low PWM signal, where the active state is a lower signal level. The second PWM signal is a low-to-high PWM signal where active state is a higher signal level. The first and second PWM signals are combined to provide a summed signal, which is filtered to generate a sinusoidal signal. The DC offset of the first PWM signal varies inversely to the DC offset of the second PWM signal. In this manner, distortions caused by variations in the DC offset present in the generated sinusoidal signal are limited (i.e., reduced or eliminated).
Abstract: A cable includes a channel with an aspect ratio that houses optical fibers therein. The cable includes first and second stranded conductors on opposing sides of the channel. The channel is arranged with respect to the stranded conductors so that the fibers assume low strain positions in the channel when the cable is bent.
