摘要： A multi-band wireless access point includes a first antenna system including at least one antenna and having a first effective range for communicating with subscribers using a first communications protocol and a second antenna system including a plurality of antennas generally co-located with the first antenna system and having a second effective range for communicating with subscribers using a second communications protocol whereby the first and the second effective ranges are effectively coextensive. Moreover, each of the plurality of antennas in the second antenna system has a greater directivity than the at least one antenna in the first antenna system to compensate for a difference in propagation of the second communications protocol relative to the first communications protocol.

摘要： A helical corrugated coaxial cable possesses low cost of manufacture comparable to that of braided shield coaxial cable, electrical performance comparable to solid tubular shielded cable, flexibility of helical and annular corrugated cable, and fluid blockage comparable to annular shielded cable. The cable has an inner conductor surrounded by a foam dielectric insulator. A tubular shield surrounds the dielectric and has helical corrugations penetrating into and compressing the foam dielectric to effectively suppress the formation of fluid migration air gaps or passageways between the shield and the dielectric. The shield is preferably composed of aluminum or aluminum alloy. Alternatively, the shield may be annularly corrugated for improved water blocking performance. The manufacturing process employs high speed welding and multi-lead corrugating operations to reduce cost.

摘要： Signal handling equipment, such as a high power amplifier, is implemented with feed-forward compensation circuitry that adjusts the effective operation of the equipment (e.g., linearizes the amplifier). The compensation circuitry includes (i) a nulling loop, which generates an error signal based on the output from the amplifier, and (ii) an error loop, which generates, based on the error signal, a feed-forward compensation signal that is added to the output of the amplifier. The compensation circuitry is tuned by tuning the nulling loop and then iteratively tuning the error loop based on data generated by perturbing the tuning of the nulling loop. In one implementation, data corresponding to the amplitude of the output signal is analyzed to generate metric values that are used to iteratively adjust the tuning of the error loop.

摘要： A locking mechanism for a coaxial connector assembly of the type wherein an inner cylindrical connector member of a female connector is adapted for receipt within an outer connector member of a male connector. The locking mechanism is positionable between the male and female connectors and includes one or more locking balls disposed within a sleeve portion of the male connector. The sleeve is of the push-pull variety and incorporates an internal surface for biasing the locking ball or balls into a recess formed in the female connector. When the sleeve is in a locked position, the locking ball or balls captured therein are biased radially inwardly therefrom to urge the male and female connectors into a tighter engagement.

摘要： A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by friction welding is provided with a monolithic connector body with a bore dimensioned for an interference fit with an outer diameter of the outer conductor. A friction groove may be formed around the leading end of the outer conductor by application of a friction weld support against the inner diameter and leading end of the outer conductor. The friction groove may include a material chamber formed between a radial friction protrusion of the bore and a bottom of the friction groove. The friction weld support may be provided with ceramic surfaces contacting the outer conductor, a stop shoulder dimensioned to abut a cable end of the bore and/or an elastic insert seated within an inner conductor bore.
