SMA attenuator, 20dB, 2W, DC–18 GHz – Precision Wideband Performance

SMA 20dB Coaxial RF Attenuator, 2W, DC–18 GHz – Precision Wideband Performance

This SMA 20 dB coaxial attenuator is a precision RF component designed for reliable wideband operation from DC to 18 GHz. With 2 W continuous power handling and a VSWR of 1.25 typ., it provides stable attenuation and consistent performance in demanding RF test and system environments.

The attenuator uses SMA precision connectors and a robust coaxial design to ensure excellent repeatability when inserted into RF signal paths. It is ideal as a fixed 20 dB RF attenuator for level setting, impedance matching, input protection and linearity optimisation in RF laboratories, wireless systems and telecom infrastructure. Each unit is tested to guarantee predictable behaviour across the full DC–18 GHz band.

This SMA RF attenuator is a reliable choice for engineers and technicians looking for a high-quality coaxial attenuator with predictable 20 dB attenuation, professional documentation and immediate availability from stock.
