Coaxial Fixed Attenuator, DC to 18 GHz

The Keysight 8491B coaxial fixed attenuator provides precision attenuation, flat frequency response and low SWR over broad frequency ranges. The attenuator is available in nominal attenuations of 3 dB and 6 dB, as well as 10 dB increments from 10 dB to 60 dB. It has type-N connectors with a maximum frequency of 18 GHz. This attenuator is swept-frequency tested to ensure specification compliance at all frequencies. Calibration points are provided on a nameplate chart attached to each unit.
