General Specifications for 20 dB, 100W, DC to 18 GHz Attenuator:

• Frequency Range:

  • DC to 18 GHz, covering a wide range of RF and microwave frequencies. This allows the attenuator to handle signals from low frequencies (DC) up to 18 GHz, making it suitable for high-frequency applications in telecommunications, testing, and radar systems.

• Attenuation:

  • 20 dB nominal attenuation, which means the input signal is reduced by a factor of 100 (a 20 dB decrease).

• Power Handling:

  • 100W continuous average power handling capacity, which allows it to handle higher power RF signals without degrading performance or causing damage.
  • Can also handle short-term power surges or pulse power (with proper heat dissipation).
