STA-30-10-FS-40 is a 10 watt fixed attenuator that is used in millimeterwave systems and operates from 75 to 110 GHz. The attenuator has a nominal fixed attenuation value of 30 dB across the entire W band. The attenuator is uniquely designed and fabricated for full waveguide band applications and displays an extremely flat frequency response across the full bandwidth. Various attenuation values are available under different model numbers.
