Description
Fixed Attenuator | N Male to N Female | 3 dB | 10 Watts | Screw-lock | Brass Copper-Tin-Zinc Alloy Body
The ROSNOL FA-N1N25A-4G10W3/144-94 is a precision 3 dB fixed attenuator designed for RF communication, broadcasting, wireless infrastructure, aerospace, defense, and test & measurement applications. Operating from DC to 4 GHz with 50 Ω impedance, VSWR ≤ 1.2, 10 W average power handling, and 500 W peak power capability, this attenuator provides controlled signal reduction while maintaining signal integrity. Fixed attenuators are commonly used to reduce signal levels, improve impedance matching, minimize reflections, protect sensitive RF equipment, and optimize system performance.Constructed with brass bodies plated with Copper-Tin-Zinc alloy, gold-plated brass and beryllium copper contacts, PTFE insulators, and silicone rubber gaskets, the attenuator delivers reliable performance and long service life. The nominal attenuation is 3 dB with ±0.5 dB accuracy.
Manufactured in Taiwan, ROSNOL RF attenuators support customers throughout North America, Europe, and Asia-Pacific. All products are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH requirements.
