Keysight (Agilent) 84904L Programmable Step Attenuator, DC to 40 GHz, 0 to 11 dB, 1 dB steps
Description of Keysight (Agilent) 84904L:
The Agilent 84904L 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 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 with only 2.4 dB of loss at 40 GHz. The compact size of the unit, 35% smaller than the Agilent 8495/7 (26.5 GHz) family, allows for easy integration into instruments and ATE systems. Superior RF Performance of Keysight (Agilent) 84904L:
- Frequency range: dc to 40 GHz
- Insertion loss at 0 dB: 0.8 dB + 0.04 dB/GHz
- Maximum SWR: 1.3 to 12.4 GHz, 1.7 to 34 GHz, 1.8 to 40 GHz
Repeatability and Life Span of Keysight (Agilent) 84904L:
- Repeatability life: 0.03 dB max 5 million cycles per section, typical
- 5 million cycles per section
Power Handling of Keysight (Agilent) 84904L:
- Maximum RF input power: 1 W (average), 50 W (peak)
Features of Keysight (Agilent) 84904L:
