SMA attenuator, 6 dB, 10 W, DC–4 GHz – Compact RF Power Series

SMA 6 dB Coaxial RF Power Attenuator, 10 W, DC–4 GHz – Compact RF Power Series

This SMA 6 dB coaxial attenuator is designed for compact RF power applications requiring stable attenuation, low VSWR and robust thermal performance. Operating from DC to 4 GHz with a continuous power rating of 10 W, it provides consistent and predictable behavior in laboratory test benches, telecom systems and wireless RF setups.

With a low VSWR of ≤ 1.15, this SMA attenuator ensures excellent impedance matching and reduced signal reflections across the entire operating band. The bidirectional design allows reliable RF power operation in both directions, making it suitable for amplifier testing, system calibration, level control and input protection in sensitive RF modules.

The attenuator features a rugged SMA male–female interface and a finned aluminium heatsink for improved thermal dissipation during continuous 10 W RF loads. Built with precision resistive elements and high-quality materials, it delivers long-term stability and mechanical reliability in demanding field and laboratory environments.
