    • Disclosed herein is an asymmetric power divider. The asymmetric power divider includes a power dividing unit, a first matching network, and a second matching network. The power dividing unit supplies different amounts of power to a carrier amplifier and a peaking amplifier, which are connected in parallel. The first matching network is connected between the power dividing unit and the carrier amplifier so as to perform impedance matching between the power dividing unit and the carrier amplifier. The second matching network is connected between the power dividing unit and the peaking amplifier so as to perform impedance matching between the power dividing unit and the peaking amplifier.
    • 本文公开了一种不对称功率分配器。 不对称功率分配器包括功率分配单元,第一匹配网络和第二匹配网络。 功率分配单元向并联的载波放大器和峰化放大器提供不同的功率量。 第一匹配网络连接在功率分配单元和载波放大器之间,以便在功率分配单元和载波放大器之间执行阻抗匹配。 第二匹配网络连接在功率分配单元和峰化放大器之间,以便在功率分配单元和峰化放大器之间执行阻抗匹配。

    • Glasses having a frame for a combined use with a cap which can be attached to the visor of the cap, or when the cap is not worn, can be worn as an ordinary pair of glasses. The glasses having a frame for a combined use with a cap include the main body of glasses having a reinforce unit integrally formed with the glasses, on top of a lens unit to which clips or earpieces are coupled; a central frame which is fixedly coupled to the center of the reinforce unit of the main body of glasses; and a pair of clips and a pair of earpieces that are coupled to both ends of the reinforce unit of the main body of glasses and the central frame, and by doing so, strengthen the coupling power of the clips and the earpieces such that even when the user performs heavy exercise or the shape of the visor of a cap is changed by an external impact, the clips or earpieces are not separated from the main body of glasses and the central frame, and the clips and the earpieces can be easily attached and detached.
    • 具有用于与盖组合使用的框架的眼镜,其可以附接到帽的遮阳板,或者当帽没有被佩戴时,可以作为普通的一副眼镜佩戴。 具有用于与盖组合使用的框架的眼镜包括具有与眼镜一体形成的加强单元的玻璃主体,在与夹子或耳机耦合的透镜单元的顶部上; 中央框架,其固定地联接到眼镜主体的加强单元的中心; 以及耦合到眼镜主体和中央框架的加强单元的两端的一对夹子和一对耳机,并且通过这样做,加强夹子和耳塞的联接力,使得即使当 使用者进行大量的运动或帽子的遮阳板的形状由于外部的冲击而改变,夹子或耳塞不会与眼镜主体和中央框架分离,并且夹子和耳塞可以容易地附着, 分离
