Description
N Fixed Attenuator | 40 dB | 25W | DC–4 GHz
The ROSNOL FA-N1N25A-4G25W40/H33-H3 Fixed Attenuator is engineered for RF systems that require substantial signal suppression while maintaining excellent transmission stability. Featuring an N Plug (Male) to N Jack (Female) configuration, this 50 Ω attenuator operates from DC to 4 GHz and supports 25 W average power handling. With 40 dB attenuation accuracy of ±0.8 dB and a low VSWR of ≤1.25, it helps minimize signal reflections and improve measurement consistency in demanding RF environments. Built for professional communication and testing systems, it provides dependable long-term performance.
The attenuator utilizes a gold-plated phosphor bronze center contact, nickel-plated brass body, PTFE dielectric, and black-anodized aluminum heatsink to achieve excellent conductivity, corrosion resistance, and thermal dissipation. The rugged screw-on coupling structure supports more than 500 mating cycles.
