The Keysight (Agilent HP) 8762B is a high-performance, single-pole double-throw (SPDT) coaxial switch operating from DC to 18 GHz. Designed for high isolation and low insertion loss, this terminated electromechanical switch features break-before-make RF contacts, an internal 50 Ω termination for the unused port, and automatic coil current interruption to minimize power consumption.
