The graphs on this slide show the frequency performance of all 10 attenuators in 1dB inclement. The charts show up to 40GHz. All products are within the specified attenuation tolerance: ±0.5dB (up to 20GHz), and ±0.75dB (20GHz to 30GHz) and less than 1.5 up to 20GHz and less than 1.7 between 20GHz and 30GHz in VSWR.
