Attenuators 01311 Series

Attenuators

Attenuators (D.C. to 26.5 GHz) on quartz are available in 1 dB increments from 1 dB to 20 dB. Precision attenuators may also be fabricated on alumina and aluminum nitride.



Description
The 01311 attenuator chip series is designed to achieve precision attenuation and tight-flatness with an attenuation accuracy of +/- 0.2 dB on our 1-10 dB pads and +/- 0.3 dB on our 11-20 dB pads. All 01311 attenuator chips are 100% probed.

Fused Silica Dielectric
Die Size: L = .080 W =.100 T = .010
Tolerance: L = W = +/- .001 T= +/- .0005
