摘 要：
A signal switching device is disclosed that is capable of transmitting signals with less signal loss while securing a good isolation characteristic. The signal switching device includes a first section (3106) formed from a superconducting material
connected to a first transmission path (3104). The first section (3106) has a smaller cross section at the input end than at the output end. Or, the signal switching device may include a first section formed from a superconducting material connected to a first transmission path in series, and a second section formed from a superconducting material connected to a second transmission path in parallel. The cross section of the
second section is smaller than that of the second transmission path. The length of
