The STA-60-12-D1 from Sage Millimeter is direct reading, rotary vane attenuator that operates from 60 to 90 GHz. The attenuator has a has a large scale dial which indicates the attenuation value being provided by the attenuator. This is ideal for equipment in waveguide systems where a broad direct reading of attenuation is required. It provides an attenuation range of up to 60 dB with an accuracy of 0.1 dB or 3% of the reading, whichever is larger, up to 40 dB, 5% up to 50 dB, and “for reference only” above 50 dB.
