Description
N Male to N Female Fixed Attenuator | 20 dB | 500 W | Screw-lock | Stainless Steel Body
The ROSNOL FA-N2N25A-10G500W20/9X-9X is a precision-engineered fixed attenuator designed for high-power RF and microwave applications up to DC to 10 GHz. This N-type attenuator provides a nominal attenuation of 20 dB with an attenuation deviation of −4 dB / +3 dB, delivering controlled signal reduction at very high power levels. Rated for 500 watts average power with VSWR ≤ 1.35 (Return Loss ≥ 16.5 dB), it ensures stable impedance matching across wideband frequencies. The screw-lock coupling mechanism supports secure installation and repeatable mechanical performance.Constructed with a passivated stainless steel body, this attenuator features beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating for optimal electrical conductivity and long-term durability. PTFE insulation provides excellent dielectric performance, while a silicone rubber gasket enhances environmental sealing. An aluminum heat sink with black anodized finish improves thermal dissipation under continuous power load. Mechanical specifications include ≥ 500 mating cycles, coupling nut retention ≥ 450 N, axial captivation ≥ 28 N, and a maximum coupling torque of 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.
