Introduction
The Keysight Technologies, Inc. 8490D family is a line of precision fixed coaxial attenuators with performance specified up to 50 GHz. These attenuators use the 2.4 mm coaxial connector, which exhibits excellent performance from dc to 50 GHz. The 8490D family has attenuation values of 3, 6, 10, 20, 30, and 40 dB.
The Keysight 8490D family of 2.4 mm fixed coaxial attenuators is assembled and tested with the same meticulous care as their lower frequency counterparts: the Keysight 8491, 8492, and 8493 families. These attenuators are all tested on Keysight precision analyzers to assure specifications over the full frequency range.
