Description
N Female to N Female Fixed Attenuator | 30 dB | 100 W | Screw-lock | Brass Body
The ROSNOL FA-N2N25A-6G100W30/H3-H3 is a precision-engineered fixed attenuator designed for RF and microwave systems requiring stable attenuation performance up to DC to 6 GHz. This N-type attenuator provides a nominal attenuation of 30 dB with an attenuation deviation of ±1.2 dB, ensuring consistent signal control and predictable power reduction. Rated for 100 watts average power at 25°C and specified with VSWR ≤ 1.35 (Return Loss ≥ 16.54 dB), it delivers reliable impedance matching. The screw-lock coupling mechanism ensures secure mechanical connection and repeatable mating performance.Manufactured with a nickel-plated brass body, this attenuator features a phosphor bronze center contact with gold plating over a non-magnetic nickel-phosphorus underplating to optimize conductivity and corrosion resistance. PTFE insulation provides excellent dielectric stability, while an aluminum heatsink with black anodized finish enhances thermal dissipation. Mechanical integrity includes mating cycles ≥ 500, coupling nut retention ≥ 450 N, axial captivation ≥ 28 N, and a maximum coupling torque of 1.70 Nm (recommended 0.7–1.1 Nm). The operating temperature range is −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.
