2.92mm Plug (Male) to 2.92mm Jack (Female) Fixed Attenuator, 40GHz 2W 1dB VSWR 1.3

2.92mm Fixed Attenuator | Male to Female | 1 dB | 2 Watt | Screw-Lock | Stainless Steel Body Passivated

The ROSNOL FA-K1K25A-40G2W1/9XX-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 1 dB with accuracy of ±0.6 dB, delivering stable signal control for high-frequency applications. 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) for superior conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, and silicone rubber gaskets provide environmental sealing. The assembly withstands temperatures from −55°C to +125°C, ensuring long-term reliability under harsh conditions.

ROSNOL’s RF attenuators deliver exceptional performance at competitive pricing, making them a cost-effective alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for attenuation values, materials, and plating options are available to meet specialized requirements.
