Attenuators

The 01311 attenuator chip series is designed to achieve precision 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. Ion Beam Milling tests 100% of all attenuator chips prior to shipment to verify that they meet specifications.
