The Keysight (Agilent) 8762B is an electromechanical latching coaxial switch that routes DC to 18 GHz signals in single-pole double-throw (SPDT) configuration. This terminated 50 Ohm switch delivers break-before-make switching action with isolation exceeding 100 dB to 4 GHz and 90 dB to 18 GHz, insertion loss below 0.25 dB to 2 GHz and 0.5 dB to 18 GHz, and SWR performance ranging from 1.10 to 1.30 across its frequency span. Mechanical latching eliminates continuous drive current after the 30 ms switching cycle, reducing power consumption in automated test and measurement systems.
