Description
N Male to N Female Fixed Attenuator | 30 dB | 500 W | Screw-lock | Stainless Steel Body
The ROSNOL FA-N2N25A-10G500W30/9X-9X is a high-power fixed attenuator engineered for RF systems operating up to DC to 10 GHz. This N-type attenuator provides a nominal attenuation of 30 dB with an attenuation deviation of −4 dB / +3 dB, ensuring effective signal attenuation under demanding conditions. Rated for 500 watts average power and specified with VSWR ≤ 1.35 (Return Loss ≥ 16.5 dB), it maintains reliable impedance control at microwave frequencies. The screw-lock coupling mechanism provides secure and repeatable mating during installation and maintenance.The attenuator body is made of passivated stainless steel and incorporates beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating to achieve low contact resistance and excellent corrosion resistance. PTFE insulation and silicone rubber sealing components support stable dielectric and environmental performance. An aluminum heat sink with black anodized finish enhances thermal management. Mechanical integrity is ensured with ≥ 500 mating cycles, coupling nut retention ≥ 450 N, axial captivation ≥ 28 N, and coupling torque ≤ 1.70 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, high-power 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.
