SMA Plug (Male) to SMA Jack (Female) Fixed Attenuator, 6GHz 2W 6dB VSWR 1.2

SMA Fixed Attenuator | 2 W Power | 6 dB | Screw-Lock | Brass Body

The ROSNOL FA-A1A25A-6G2W6/911-91 is a precision-engineered SMA fixed attenuator designed for high-frequency applications up to 6 GHz. It features a 50 Ω impedance and VSWR performance of ≤1.20 for 1–20 dB attenuation and ≤1.25 for 21–30 dB attenuation, ensuring excellent return loss (≥20.83 dB and ≥19.08 dB respectively). This device supports 2 W average power at 25°C and offers nominal attenuation of 6dB with accuracy of ±0.5 dB across the specified range. The screw-lock coupling mechanism guarantees secure mating and mechanical durability of ≥500 cycles.

Constructed with premium materials, the center contact is beryllium copper with gold plating over a nickel underlayer for superior conductivity and corrosion resistance. The body and coupling nut are brass with gold plating over nickel, while the insulator is PTFE for outstanding dielectric performance. A silicone rubber gasket ensures environmental sealing. The design is rated for reliable operation across a temperature range of -55°C to +125°C.

ROSNOL’s RF components deliver exceptional quality and cost efficiency, offering a competitive alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for attenuation values, materials, and plating are available to meet specialized requirements.
