Precision N Plug (Male) to Precision N Jack (Female) Fixed Attenuator, 18GHz 1W 3dB VSWR 1.4

Precision N Fixed Attenuator | Plug (Male) to Jack (Female) | 3 dB | 1 W Power Handling | Screw-Lock | Passivated Stainless Steel Body with Gold-Plated BeCu Contact

The ROSNOL FA-PCN1PCN25A-18G1W3/9XX-9X precision N fixed attenuator operates from DC to 18 GHz with a 50 Ω impedance and VSWR ≤ 1.4. It provides 3 dB nominal attenuation with a deviation of ±1 dB and supports 1 W average power handling. The screw-lock coupling mechanism ensures secure mating with coupling nut retention ≥ 450 N, center contact captivation (axial) ≥ 28 N, and a minimum of 500 mating cycles, delivering stable electrical and mechanical performance across RF systems.

The construction features a beryllium copper center contact with gold plating over non-magnetic nickel–phosphorus underplating, a passivated stainless steel body and coupling nut, PTFE insulator, and a silicone rubber gasket. This material stack provides excellent corrosion resistance and reliable performance across an operating temperature range of −55 °C to +125 °C.

ROSNOL’s precision-engineered RF attenuators are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Offering high quality, stable performance, and competitive pricing, ROSNOL attenuators serve as a cost-effective alternative to leading European and American brands. Customization services for attenuation values, materials, plating, and mechanical design are available upon request.
