Precision N Plug (Male) to Precision N Jack (Female) Fixed Attenuator, 18GHz 500W 20dB VSWR 1.5

Precision N Fixed Attenuator | Male to Female | 20 dB | 500 W | Brass Body

The ROSNOL FA-PCN1PCN25A-18G500W20/H33-H3 fixed attenuator covers DC to 18 GHz with 50 Ω impedance and VSWR ≤ 1.5. It provides 20 dB nominal attenuation with ±5.0 dB deviation and supports 500 W average power at 25 °C; power derates linearly to 50 W at 125 °C. Peak power capability is up to 5000 W under specified pulse conditions. The screw-lock coupling ensures secure engagement with ≥ 500 mating cycles, coupling nut retention ≥ 450 N, and axial captivation ≥ 28 N.

Materials and plating: gold-plated phosphor bronze center contact over nickel underplating; brass body and coupling nut with nickel plating; PTFE insulator; silicone rubber gasket; black anodized aluminum heatsink. The assembly maintains corrosion resistance and dielectric stability across −55 °C to +100 °C.
