The Keysight 8768K (formerly Agilent) is a high-performance, single-pole five-throw (SP5T) multiport coaxial switch operating from DC to 26.5 GHz. Engineered for ATE and high-frequency microwave applications, it utilizes proven latching technology to deliver exceptional isolation, low insertion loss, and outstanding repeatability over a lifetime of more than 5 million cycles. The switch incorporates self-interrupting contacts to minimize power dissipation and simplify driver circuitry.
