The Agilent/Keysight 8746B is a 30 dB coaxial fixed attenuator engineered for precise RF signal attenuation across DC to 18 GHz. This 50 Ω device delivers excellent attenuation flatness and low VSWR (1.3) to minimize signal distortion in high-frequency applications. The 8746B handles continuous average power input of 25 W, with peak power ratings of 500 W (DC to 5.8 GHz) and 125 W (5.8 to 18 GHz), supported by large heat-dissipating fins for sustained maximum-power operation. Attenuation accuracy of ±1 dB at 18 GHz ensures reliable performance across the full frequency range.
