Page 8: Introduction
Introduction General Information The Keysight N181x low PIM coaxial switch is designed with a rectangular coaxial structure similar to edge-line. This transmission line structure provides for movement of the edge-line center conductor between two fixed, continuous ground planes. The main advantage of this innovation is that the moving contacts can be easily activated, yet maintain high-isolation and low-insertion loss. - Page 9 Introduction Minimum switch spacing is 6.0 mm (0.25 inch). WARNING The N181x comes with current interrupt, the drive current is automatically disconnected after the switch is fully latched (15 ms). Keysight N181x Operating and Service Manual...
