Description
N Plug to N Jack Fixed Attenuator | 30 dB | 300 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-8G300W30/944-94 is a high-performance fixed attenuator designed for DC to 8 GHz operation. This N-type attenuator delivers a nominal attenuation of 30 dB with an attenuation deviation of ±1.0 dB, ensuring consistent attenuation accuracy. Rated for 300 watts average power at 25°C and specified VSWR ≤ 1.40 (Return Loss ≥ 15.56 dB), it supports dependable impedance matching. The screw-lock coupling guarantees secure engagement during frequent test cycles.Constructed with a nickel-plated brass body and beryllium copper center contact with gold plating (nickel underplated), the assembly provides robust electrical performance and corrosion resistance. PTFE insulation ensures dielectric stability, and silicone rubber gaskets improve environmental sealing.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available.
