Description
Precision N Fixed Attenuator | Male to Female | 20 dB | 100 W | Stainless Steel Body
The ROSNOL FA-PCN1PCN25A-18G100W20/9XX-9X fixed attenuator supports DC to 18 GHz operation with 50 Ω impedance and VSWR ≤ 1.35. It delivers 20 dB nominal attenuation with ±2 dB deviation and handles 100 W average power at 25 °C, with peak power up to 1000 W for pulsed operation. The screw-lock interface provides secure mating, ≥ 500 mating cycles, coupling nut retention ≥ 450 N, and robust mechanical durability for high-power RF systems.Piece-part construction features a beryllium copper center contact with gold plating over non-magnetic nickel–phosphorus underplating, passivated stainless steel body and coupling nut, PTFE insulator, and silicone rubber gasket. Material selection ensures long-term corrosion resistance and electrical stability from −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.
