Description
Precision N Fixed Attenuator | Male to Female | 10 dB | 5 W | Stainless Steel Body
The ROSNOL FA-PCN1PCN25A-18G5W10/933-93 fixed attenuator operates from DC to 18 GHz with a characteristic impedance of 50 Ω and VSWR ≤ 1.4. It provides 10 dB nominal attenuation with ±1.0 dB accuracy and supports 5 W average power handling at 25 °C. The screw-lock coupling mechanism ensures secure engagement, with ≥ 500 mating cycles, coupling nut retention ≥ 450 N, center contact captivation (axial) ≥ 28 N, and recommended torque 0.7–1.1 Nm.Piece-part construction includes a beryllium copper (BeCu) center contact with gold plating over nickel underplating, a brass body and coupling nut with nickel plating, PTFE insulator, silicone rubber gasket, and a black anodized aluminum heatsink for thermal management. The assembly delivers corrosion resistance and stable dielectric performance across −55 °C to +125 °C.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL attenuators offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
