The NFA18K25 is a fixed attenuator designed for DC to 18 GHz applications, offering attenuation from 10 to 60 dB with 50 Ω impedance. It features a robust 250 W average power rating at 25°C, derated linearly to 12.5 W at 120°C, and supports peak power up to 5 kW at DC to 12.4 GHz or 1 kW at 18 GHz under specified pulse conditions. The unit is housed in a case measuring 254 × 120 × 110 mm with N-type connectors. Operating temperature ranges from -55°C to +125°C, and VSWR varies from 1.2 to 1.45 depending on frequency and attenuation level. It is suitable for wireless, radar, and laboratory test environments.
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.
