Description
2.92mm Fixed Attenuator | Male to Female | 0 dB | 1 Watt | Screw-Lock | Stainless Steel Body Passivated
The ROSNOL FA-K1K25A-40G1W0/9XX-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 ≤ 1.4 (≥15.56 dB return loss). This model offers a nominal attenuation of 0 dB with tolerance ±1 dB at 3.6 GHz, ±1.2 dB at 10–20 GHz, and ±1.5 dB at 30 GHz, delivering stable signal integrity for high-frequency applications. Rated for 1 Watt average power at 25°C, 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 over nickel underplating for superior conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, while 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.
