The attenuator has a fixed attenuation value of 40 dB at center frequency, 50 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-19-F1, where XX is the desired attenuation value.
