    摘要： An antenna minimizes radiation from the outer conductor (44) of a coaxial cable (40) that is coupled to the antenna by providing a balancing tab (90) that lies near the connection (72) of the cable outer conductor (44) to the antenna. One antenna includes a Yagi structure (12) constructed of a plate of metal that forms a long boom (20) and a plurality of directors (28) extending laterally across the boom, with an electrical coupling loop mounted at a rear region of the Yagi structure. The coupling loop includes a folded dipole in the form of a metal coupling plate that forms a loop (54) with a gap (70), the loop having a laterally elongated front loop end (60). The Yagi structure is formed with a balancing tab (90) that lies forward of the loop, that has a lateral length (D) less than half that of one of the directors, and that extends from only one side (22) of the boom which is the side to which the outer coax conductor (44) is connected to the loop. The metal coupling plate lies facewise adjacent to a face (24) of the Yagi plate, with a dielectric spacer (76) between them.

    摘要： An amplifier is provided for optimizing gain. The amplifier determines an optimal gain from inputs including the forward link and reverse link input power. The inputs are processed to determine an optimal gain of the amplifier. The optimal gain may be accessed from a lookup table that accounts for characteristics of the amplifier, the cell phone (or other device), and the base station (or base stations). The optimal gain is set to account at least for industry standards, amplifier oscillation issues, base station overload protection, and base station noise floor protection.

    摘要： A method is provided for detecting and mitigating oscillation in an amplifier. The amplifier is configured to sample a signal being amplified to determine whether the amplifier is oscillating. In addition, the status of the amplifier can be verified based on the apparent signal levels of the signals being amplified. The gain of the amplifier is then adjusted in accordance with whether the amplifier is oscillating or as necessary to maintain gain that is compatible with the system within which the amplifier is operating.
