Description
2.4 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 20 dB | 1 W | Screw-Lock | Stainless Steel Body
The ROSNOL FA-Q1Q25A-50G1W10/9XX-9X is a precision 50 Ω fixed attenuator designed for broadband RF and microwave applications from DC to 50 GHz. It provides a nominal attenuation of 20 dB with ±0.8 dB accuracy and maintains a VSWR of ≤ 1.30, ensuring stable signal conditioning across ultra-high frequencies. Rated for 1 W average power and 100 W peak power, this attenuator supports consistent performance in compact high-frequency systems. The 2.4 mm connectors deliver excellent high-frequency performance up to 50 GHz and are mechanically compatible with 1.85 mm interfaces, offering flexibility in precision measurement setups.Constructed with stainless steel passivated bodies, this attenuator provides excellent corrosion resistance and mechanical durability. The center contacts are made of beryllium copper with gold plating, ensuring high conductivity, low contact resistance, and long-term reliability. PEI insulators provide stable dielectric performance across wide temperature ranges. Stainless steel construction offers superior environmental resistance, though at higher cost compared to brass alternatives.
ROSNOL’s fixed attenuators are engineered for precise signal control in demanding RF and microwave systems. Designed for broadband accuracy and stability, ROSNOL attenuators provide a reliable and cost-effective alternative to leading global brands. All products are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Custom attenuation values, power ratings, and mechanical configurations are available upon request.
