The Rohde & Schwarz DNF attenuators are characterized by very low attenuation errors, largely frequency-independent attenuation and low ripple. They are highly stable, vibration-resistant (according to MIL-A-3933), have a low temperature dependency and withstand even short-term overloads.
This variant of the R&S DNF attenuator has the following properties: 3 dB, 50 Ohm, 2 W, DC - 12.4 GHz, Type-N (m) to Type-N (f).
