Coaxial Fixed Attenuator, DC to 50 GHz

The Keysight 8490D coaxial fixed attenuator provides precision attenuation, flat frequency response, low SWR over broad frequency range at a low price. The attenuator is available in nominal attenuations of 3 dB and 6 dB, also 10 dB increments from 10 dB to 40 dB. This attenuator is swept-frequency tested to ensure they meet specifications at all frequencies. Calibration points are provided on a nameplate chart attached to each unit.
