The NFA18K3 is a fixed coaxial attenuator designed for DC to 18 GHz applications requiring high power handling, such as wireless transmitters, radar, and laboratory testing. It features N-type male and female connectors, 50 Ω impedance, and supports attenuations of 3 dB, 6 dB, or 10-60 dB. The device handles up to 300 W average power at 25°C, derating linearly to 15 W at 120°C, with peak power ratings of 5 kW (5 µs pulse, 3% duty cycle) up to 12.4 GHz and 1 kW (5 µs pulse, 15% duty cycle) at 18 GHz. VSWR ranges from 1.20 to 1.45 depending on frequency and attenuation. It operates from −55°C to +125°C. Physical dimensions and exact outline are determined by attenuation and frequency variant, with three available mechanical outlines (A, B, C).
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.
