F-Band Fixed Attenuator, High Precision

STA-03-08-F1 is a 3 dB fixed attenuator that is used in millimeterwave systems and operates from 90 to 140 GHz. The attenuator has a fixed attenuation value of 3 dB at center frequency, 115 GHz. The attenuator’s waveguides are manufactured with precision wire EDM to ensure high accuracy and a quality internal surface finish. The design features anti-cocking flanges to reduce misalignment errors and a sandblasted surface treatment to provide a durable finish. While the attenuator is designed for full waveguide band applications, the attenuation value does show a minor slope within the band due to its distinct mechanical configuration. Other attenuation values are available under different model numbers as STA-XX-08-F1, where XX is the desired attenuation value.
