The Keysight 11922A is a precision coaxial adapter engineered for high-frequency measurements of 50-ohm devices up to 50 GHz. It bridges 1.0 mm male and 2.4 mm male connectors, enabling seamless integration across test configurations where connector compatibility is critical. The adapter’s air dielectric interface and low-loss plastic bead center conductor support deliver minimal signal degradation across DC to 50 GHz operation.
