84906L Programmable Step Attenuator, DC to 40 GHz, 0 to 90 dB, 10 dB Steps

Загрузить техническое описание

The Keysight 84906L programmable step attenuator offers coaxial measurements to 40 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 an attenuation range of 0 to 90 dB in 10-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 with only 2.4 dB of loss at 40 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.
