Precision N Plug (Male) to Precision N Jack (Female) Fixed Attenuator, 18GHz 200W 40dB VSWR 1.5

Precision N Fixed Attenuator | Male to Female | 40 dB | 200 W | Brass Body

The ROSNOL FA-PCN1PCN25A-18G200W40/H33-H3 fixed attenuator operates from DC to 18 GHz with 50 Ω impedance and VSWR ≤ 1.5. It provides 40 dB nominal attenuation with a deviation of −2.0/+3.5 dB and supports 200 W average power handling at 25 °C. The screw-lock coupling ensures secure engagement, ≥ 500 mating cycles, coupling nut retention ≥ 450 N, and axial captivation ≥ 28 N, enabling repeatable attenuation stability across the band.

Construction employs a gold-plated phosphor bronze center contact over nickel underplating, brass body and coupling nut with nickel plating, PTFE insulator, silicone rubber gasket, and a black anodized aluminum heatsink for thermal management. The assembly provides corrosion resistance and dielectric stability over −55 °C to +100 °C.
