The Keysight 84904K programmable step attenuator offers coaxial measurements to 26.5 GHz in a compact, rugged design. It offers repeatability of better than 0.03 dB, excellent life (greater than 5 million switching cycles per section) and attenuator range of 0 to 11 dB in 1-dB steps. This latest design evolution sets new standards for size and performance. High attenuation accuracy and low SWR are achieved through the use of miniature thin-film attenuation cards composed of high-stability tantalum nitride film of saphire substrate. Insertion loss is outstanding, with less than 2 dB of loss at 26.5 GHz. The compact size of the unit, 35% smaller than the Keysight 8495/7 (26.5 GHz) family, allows for easy integration into instruments and ATE systems.
