Design of 0.35–1.5 GHz 16-input and 8-output switch matrix with 5 × 5 chessboard structure

This Letter presents a 0.35-1.5 GHz 5 × 5 switch matrix chip with a chessboard structure. In the proposed structure, by reassigning the position and switch mode of 25 passive switch grids which almost consume no DC power, the switch matrix can choose and transmit any eight of 16 input signals to the output ports on four directions at the same time. Throughput and the expansion ability of the switc...
