Description
Precision N Fixed Attenuator | Male to Female | 30 dB | 50 W | Brass Body
The ROSNOL FA-PCN1PCN25A-18G50W30/H33-H3 fixed attenuator operates from 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 handling at 25 °C, with peak power up to 1000 W under short-pulse conditions. The screw-lock coupling mechanism ensures reliable engagement with ≥ 500 mating cycles, coupling nut retention ≥ 450 N, and center contact captivation (axial) ≥ 28 N, delivering consistent attenuation and power stability.Construction utilizes a gold-plated phosphor bronze center contact over non-magnetic nickel–phosphorus underplating, brass body and coupling nut with nickel plating, PTFE insulator, silicone rubber gasket, and a black anodized aluminum heatsink to enhance thermal dissipation. The assembly ensures corrosion resistance and stable dielectric performance across an operating temperature range of −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.
