Description
2.92mm Fixed Attenuator | Male to Female | 9 dB | 2 Watt | Screw-Lock | Stainless Steel Body Passivated
The ROSNOL FA-K1K25A-40G2W9/9XX-9X is a precision-engineered fixed attenuator designed for RF and microwave systems. Operating from DC to 40 GHz, it ensures 50 Ω impedance and VSWR ≤ 1.3 (≥17.7 dB return loss). This model offers a nominal attenuation of 9 dB with accuracy of ±0.5 dB, delivering consistent signal control across the 7–10 dB accuracy band. Rated for 2 Watts average power at 25°C with peak power up to 125 Watts, the attenuator features a screw-lock coupling mechanism for secure and reliable connections.Constructed with premium materials, the center contact is beryllium copper with gold plating (3 μinch) over non-magnetic nickel‑phosphorus underplating (≈80 μinch). The body and coupling nut are stainless steel with passivated finish, complemented by silicone rubber gaskets for environmental sealing. The assembly operates reliably from −55°C to +125°C.
ROSNOL’s RF attenuators combine superior quality with competitive pricing, offering a reliable alternative to leading global brands. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH, they support customization for attenuation values, materials, and plating.
