The Keysight Y1900B is a precision 1.0 mm coaxial adapter that bridges standard and ruggedized 1.0 mm connectors for demanding RF measurement environments. Operating across DC to 120 GHz with 50 Ohm impedance, it delivers insertion loss of 0.5 dB at 110 GHz and 0.7 dB at 120 GHz, with return loss of 14 dB across 75–120 GHz. The adapter handles 10 W maximum CW power and achieves —35 dB repeatability with ruggedized connectors. One end features a standard 1.0 mm female connector (IEEE 287); the other connects to ruggedized 1.0 mm female connectors. This design suits on-wafer probing, coaxial bench measurements, and other high-frequency applications requiring reliable mechanical and electrical performance across multiple thermal regimes.
