SMA attenuator, 3dB, 2W, DC–27 GHz – Extended Microwave Performance

SMA 3 dB Coaxial RF Attenuator, 2W, DC–27 GHz – Extended Microwave Performance

This SMA 3 dB coaxial attenuator is a high-performance microwave component designed for reliable wideband operation from DC to 27 GHz. Built with a rugged stainless-steel body, precision SMA connectors and high-quality internal materials, it ensures stable attenuation and consistent RF behaviour across the entire microwave range.

With 2 W continuous power handling and a maximum VSWR of 1.30, this attenuator provides predictable results in demanding RF and microwave environments. Its ±0.6 dB attenuation accuracy makes it suitable for test benches, level control, impedance matching, input protection and linearity optimisation in advanced RF systems and high-frequency front-ends.

The attenuator is fully compliant with MIL-STD-348A mechanical interface standards and uses BeCu and gold-plated contacts for excellent repeatability. Each device is individually verified to ensure correct operation up to 27 GHz, making it a dependable choice for engineers who require extended-frequency microwave performance with professional documentation and availability from stock.
