Description
N Male to N Female Fixed Attenuator | 3 dB | 25 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-4G25W3/144-94 is a precision 3 dB fixed attenuator designed for RF communication, wireless infrastructure, broadcasting, aerospace, defense, and test & measurement systems. Operating from DC to 4 GHz with 50 Ω impedance, VSWR ≤ 1.25, and 25 W average power handling, this attenuator provides accurate signal reduction while preserving signal integrity. Fixed attenuators are used to reduce signal levels, improve impedance matching, minimize reflections, protect sensitive RF equipment, and optimize overall system performance.Constructed with brass bodies plated in Copper-Tin-Zinc alloy, gold-plated brass and beryllium copper contacts, PTFE insulators, silicone rubber gaskets, and a black anodized aluminum heatsink, the attenuator delivers reliable long-term performance. The nominal attenuation is 3 dB with ±0.5 dB accuracy.
Manufactured in Taiwan, ROSNOL RF attenuators serve customers across North America, Europe, and Asia-Pacific. All products are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH requirements.
