The NFA1820 is a fixed attenuator designed for DC to 18 GHz applications, including wireless, radar, and laboratory testing, with 20 W average power handling at 25°C derated linearly to 1 W at 120°C. It features SMA or N connectors, 50 Ω impedance, and attenuation values from 1 to 60 dB. The device operates over a temperature range of -55°C to +125°C and supports peak power up to 500 W at 2 µs pulse width and 1% duty cycle for SMA, or up to 5000 W under specified conditions for N connectors. VSWR ranges from 1.2 to 1.45 depending on frequency, connector type, and attenuation level, with attenuation accuracy varying by frequency and attenuation setting.
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.
