Features

• Models from 33 GHz to 500 GHz
• Up to 50dB Calibrated Attenuation Range
• Low VSWR
• ±10% Attenuation Flatness across full waveguide band

 

The Flann Series 024 USB Control Variable Waveguide Attenuator expands upon our range of variable attenuators to provide a compact, low cost solution. An improved RF design enables an attenuation flatness of ±10% across the full waveguide band, within its guaranteed attenuation range.

USB control provides quick and repeatable change in attenuation while also allowing the possibility to seamlessly incorporate the unit into larger and/or OEM systems.

This new attenuator provides a solution where Flann’s market-leading high precision variable attenuator is either too large or too costly for the required application.

Enhanced possibility of full band attenuation mapping to allow attenuation correction through the supply of .s2p files where requested.
