Description
Precision N Fixed Attenuator | Male to Female | 50 dB | 250 W | Brass Body
The ROSNOL FA-PCN1PCN25A-18G250W50/H33-H3 fixed attenuator supports DC to 18 GHz operation at 50 Ω with VSWR ≤ 1.55. It delivers 50 dB nominal attenuation with a deviation of −2.5/+3.5 dB and handles 250 W average power at 25 °C (peak power to 1000 W). The screw-lock interface provides reliable mating, ≥ 500 mating cycles, high retention, and robust mechanical durability.Piece-part construction includes a phosphor bronze center contact plated with gold over nickel underplating, brass body and coupling nut with nickel plating, PTFE insulator, silicone rubber gasket, and a black anodized aluminum heatsink. The design ensures corrosion resistance and electrical stability over −55 °C to +100 °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.
