The Agilent/Keysight U7108A is a single-pole-eight-throw (SP8T) electromechanical coaxial switch module designed for high-density automated test and measurement applications. This latching switch routes RF signals across eight ports with all unused paths terminated in 50-ohm loads, delivering superior isolation and low insertion loss across DC to 9 GHz. The module sustains over 1,000,000 switching cycles and integrates TTL/5V CMOS control logic with opto-electronic indication and current interrupt monitoring.
