ATN-40500-08 - N attenuator, 40 dB, 500 W, DC–8.5 GHz – Ultra-High-Power RF Series

N 40 dB Coaxial RF Power Attenuator, 500 W, DC–8.5 GHz – Ultra-High-Power RF Series

This N-type 40 dB coaxial RF power attenuator is designed for demanding high-power RF and microwave environments where stability, reliability and thermal efficiency are critical. Rated for 500 W continuous power and operating from DC to 8.5 GHz, it delivers performance levels typically reserved for premium laboratory- and telecom-grade components.

The attenuator features a high-efficiency heat dissipation architecture engineered to maintain stable operation under continuous RF load. The rugged construction, precision machining and carefully matched resistive network ensure reliable performance in transmitter test benches, high-power RF systems, EMC setups and industrial microwave installations.

With a typical VSWR of 1.25 across the full operating band, the unit provides excellent impedance matching and minimized signal reflections, supporting accurate measurements and protecting connected RF equipment from mismatch stress. This level of performance is exceptional for a 500 W attenuator extending up to 8.5 GHz.

Built with robust N-type male–female connectors and a solid mechanical body, the attenuator is designed for long-term reliability in continuous-duty applications. Each unit undergoes strict RF testing to verify stable attenuation, thermal performance and wideband behavior across the DC–8.5 GHz range.

This 500 W attenuator represents the high end of our product range and is suitable for professional RF environments requiring extreme power handling, wideband coverage and consistent attenuation. It is an ideal choice for engineers and technicians who require a dependable high-power solution without compromising performance.
