PROBLEM TO BE SOLVED: To provide a multiport switch capable of facilitating impedance matching in a combination of output ports through which an input signal passes.SOLUTION: A multiport switch includes: an input port 1; output port 2, 2, ..., 2; switches 3, 3, ..., 3, which are arranged in parallel with the input port 1 and in which each end on the output port side is connected to the output ports 2, 2, ..., 2respectively; and a variable impedance conversion circuit 4 arranged between the input port 1 and the switches 3, 3, ..., 3. When the input signal from the input port 1 is output to the selected one or more arbitrary output ports, the variable impedance conversion circuit 4 changes the impedance viewing the variable impedance conversion circuit 4 from the input port 1 side to the impedance of the input port 1.SELECTED DRAWING: Figure 1 |
