摘要:
A semiconductor device comprises: a first semiconductor chip having a control circuit; a plurality of second semiconductor chips whose operation is controlled by the control circuit; and a resin sealing body for sealing the first semiconductor chip and the plurality of second semiconductor chips, wherein: the first semiconductor chip is arranged in the central portion of the resin sealing body; and the plurality of second semiconductor chips are arranged on a periphery of the first semiconductor chip. A fuse element is further arranged outside the plurality of second semiconductor chips.
摘要:
Array antenna apparatus can form a beam in plural directions by changing the electrical supply track length between antenna elements of array antennas so that a beam of the same form but a different inclination angle is formed by each array antenna. Each array antennas can be arbitrarily selected switch circuit, and a supplied transmitted signal, and enables forming a beam in different directions alternatively.
