<p>PROBLEM TO BE SOLVED: To provide a wiring board allowing for switching between two pairs of differential lines on its single board.SOLUTION: A wiring board (100) includes: differential lines (11, 12) for respectively transmitting first and second differential signals; differential lines (13, 14) for transmitting either the first or second differential signal; a control signal transmission line (15) for transmitting a control signal; and a differential line switching part (10) composed of a high frequency switch (IC1) to which the differential line (11) and the control signal transmission line (15) are connected and a high frequency switch (IC2) to which the differential line (12) and the control signal transmission line (15) are connected. The differential line switching part (10) switches between a first state where the differential line (11) is connected to the differential line (13) and the differential line (12) is connected to the differential line (14) and a second state where the differential line (11) is connected to the differential line (14) and the differential line (12) is connected to the differential line (13) in accordance with the level of the control signal.</p> |
