Agilent / HP 84907L

This programmable step attenuator offers coaxial measurements to 40GHz in a compact, rugged design.

It offers repeatability of better than 0.03dB, excellent life greater than 5 million switching cycles per section) and an attenuation range of 0 to 70dB in 10dB 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 2,4dB of loss at 40GHz.
