ATN-0302-12 - N attenuator, 3 dB, 2 W, DC–12.4 GHz – Wideband RF Performance

N 3 dB Coaxial RF Attenuator, 2 W, DC–12.4 GHz – Wideband RF Performance

This N-type 3 dB coaxial RF attenuator is designed for general-purpose RF applications requiring stable wideband attenuation and reliable impedance matching. With a continuous power rating of 2 W and an operating range from DC to 12.4 GHz, it offers dependable performance for laboratory measurements, RF test benches, instrumentation setups and sub-12 GHz wireless systems.

Despite its low-power rating, this attenuator features a full-size N-type mechanical design, providing excellent robustness, connector stability and improved handling during frequent use. The thick knurled coupling nut offers a solid and professional feel, enhancing durability and making it suitable for repeated connect/disconnect operations in demanding lab workflows.

With a typical VSWR of 1.25, the attenuator ensures consistent impedance matching and reduced signal reflections across the entire operating band. Its aluminium and brass construction provides a lightweight yet rigid body with good RF shielding and reliable long-term performance.

This 3 dB attenuator is an ideal choice for signal level adjustment, equipment input protection, line balancing and general RF conditioning tasks where N-type connectivity is required. Each unit is tested across the full DC–12.4 GHz range to guarantee predictable behaviour and repeatable measurements in professional RF environments.
