Description
Precision N Fixed Attenuator | Male to Female | 40 dB | 500 W | Brass Body
The ROSNOL FA-PCN1PCN25A-18G500W40/033-03 fixed attenuator covers DC to 18 GHz at 50 Ω with VSWR ≤ 1.6. It delivers 40 dB nominal attenuation with a deviation of +2.0/−4.0 dB and supports 500 W average power at 25 °C with linear derating to 50 W at 125 °C. The screw-lock interface provides secure mating, ≥ 500 mating cycles, coupling nut retention ≥ 450 N, and axial captivation ≥ 28 N for robust high-power operation.Materials and plating: brass center contact with silver plating; brass body and coupling nut with nickel plating; PTFE insulator; silicone rubber gasket. The mechanical design ensures stable performance and environmental durability 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.
