The NFA1825 is a fixed coaxial attenuator designed for DC to 18 GHz applications, with an average power handling of 25 W at 25°C, derated linearly to 1.25 W at 120°C. It is available with N or SMA connectors in two mechanical sizes: Φ44×89 mm or Φ44×94 mm. The attenuation range is 1 to 50 dB, with a 50 Ω impedance and VSWR up to 1.45 across the full frequency range. Operating temperature spans from -55°C to +125°C. Peak power handling varies with pulse width and duty cycle, with a maximum of 5000 W at 5 μs pulse width and 1.25% duty cycle. Attenuation accuracy ranges from ±0.4 dB at DC-4 GHz for 1-10 dB attenuation to ±1.3 dB at DC-18 GHz for 40-50 dB attenuation.
kTB Solutions supplies various high precision and high power coaxial fixed attenuators cover the frequency range DC~67GHz. The average power handling is up to 2K watts. The attenuators are used in many applications where reduction of power is needed.
