  • High-frequency switch
    Patent number: 8698574
    Abstract: According to one embodiment, a high-frequency switch includes a high-frequency switch IC chip. The high-frequency switch IC chip has a high-frequency switching circuit section including an input terminal, a plurality of switching elements, a plurality of high-frequency signal lines, and a plurality of output terminals. The input terminal is connected to each of the plurality of output terminals via each of the plurality of switching elements with the high-frequency signal lines having the same lengths. The plurality of output terminals are arranged on a surface at an outer periphery of the high-frequency switch IC chip. The input terminal is arranged on the surface of the high-frequency switch IC chip at the center of the high-frequency switch IC circuit section.
