The Keysight 11922C is a precision coaxial adapter that interconnects test and measurement equipment for characterization of coaxial devices across millimeter-wave frequencies. Engineered for 50-ohm systems, this 1.0 mm (male) to 2.4 mm (female) adapter operates from DC to 50 GHz with low insertion loss of 0.7 dB and 20 dB return loss. The adapter is built around an air dielectric interface with a center conductor supported by a low-loss plastic bead, delivering exceptional repeatability of −35 dB at the 1.0 mm port and −44 dB at the 2.4 mm port. Maximum CW power rating is 10 W. Operating temperature range is 0 °C to 55 °C.
