Description
Precision N Fixed Attenuator | Male to Female | 30 dB | 50 W | Stainless Steel Body
The ROSNOL FA-PCN1PCN25A-18G50W30/9XX-9X fixed attenuator operates DC to 18 GHz with 50 Ω impedance and VSWR ≤ 1.4. It provides 30 dB nominal attenuation with ±1.5 dB accuracy and supports 50 W average power at 25 °C (peak power to 1000 W for short pulses). The screw-lock coupling ensures reliable engagement with ≥ 500 mating cycles, high retention, and repeatable mechanical durability.Construction employs a gold-plated BeCu center contact over nickel–phosphorus underplating, passivated stainless steel body and coupling nut, PTFE insulator, silicone rubber gasket, and a black anodized aluminum heatsink for enhanced heat dissipation. The assembly maintains corrosion resistance and dielectric stability over −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.
