    • An ultra wideband dual-frequency combiner includes a combination port (Port 1), a first port (Port 2), a second port (Port 3), two coaxial resonator band pass filters and two direct current channels. The first direct current channel is connected between the first port (Port 2) and the combination port (Port 1). The second direct current channel is connected between the second port (Port 3) and the combination port (Port 1). One end of the first coaxial resonator hand pass filters (610, 611) is electrically connected with the first port (Port 2) via a first blocking capacitor. One end of the second coaxial resonator hand pass filter (620, 621) is electrically connected with the second port (Port 3) via a second blocking capacitor. The other ends of the first coaxial resonator band pass filter and the second coaxial resonator band pass filter are connected with the combination port (Port 1) via a third blocking capacitor. The blocking capacitors are parameter distributed capacitors.
    • 超宽带双频组合器包括组合端口(端口1),第一端口(端口2),第二端口(端口3),两个同轴谐振器带通滤波器和两个直流通道。 第一个直流通道连接在第一个端口(端口2)和组合端口(端口1)之间。 第二直流通道连接在第二端口(端口3)和组合端口(端口1)之间。 第一同轴共振器带通滤波器(610,611)的一端通过第一阻塞电容器与第一端口(端口2)电连接。 第二同轴共振器带通滤波器(620,621)的一端通过第二阻塞电容器与第二端口(端口3)电连接。 第一同轴共振器带通滤波器和第二同轴共振器带通滤波器的另一端经由第三阻塞电容器与组合端口(端口1)连接。 阻塞电容器是参数分布式电容器。

    • A protective cover for protecting a panel-shaped electronic device is illustrated. The protective cover includes a polygonal frame and a number of resilient members. The frame is made of soft material and configured for surrounding and retaining the electronic device therein. The frame includes a number of corners. The resilient members entirely are received in the respective corners. Each resilient member includes a hub body and at least three distinctly oriented resilient portions extending from the hub body.
    • 示出了用于保护面板形电子设备的保护盖。 保护盖包括多边形框架和多个弹性构件。 框架由软材料制成,并且构造成用于围绕和保持电子设备。 框架包括多个角落。 弹性构件完全容纳在各个角部。 每个弹性构件包括轮毂体和从轮毂本体延伸的至少三个明显取向的弹性部分。
