SMA Plug (Male) to SMA Jack (Female) Fixed Attenuator, 6GHz 1W 2dB VSWR 1.25

SMA Fixed Attenuator | Male to Female | 2 dB | 1 Watt | Screw-Lock | Brass Body with Nickel Plating

The ROSNOL FA-A1A25B-6G1W2/933-93 is a precision-engineered fixed attenuator designed for RF and microwave applications. It operates across DC to 6 GHz with a nominal attenuation of 2dB and ensures a 50 Ω impedance for optimal signal integrity. The device offers VSWR ≤ 1.25 (≥19.08 dB return loss), insertion loss stability, and attenuation accuracy of ±0.5 dB from 1 to 30 dB. Rated for 1 Watt average power at 25°C, it features a screw-lock coupling mechanism for secure connectivity, axial contact retention ≥27 N, radial ≥3 Ncm, and mechanical durability exceeding 500 mating cycles. Recommended torque is 0.8–1.1 Nm, ensuring reliable performance in demanding environments.

Constructed with high-quality materials, the center contact is made of beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating for superior conductivity and corrosion resistance. The body and coupling nut are brass with nickel plating, while the insulator is PTFE for excellent dielectric properties. Silicone rubber gaskets provide environmental sealing, and the assembly supports a temperature range from -65°C to +155°C, guaranteeing long-term reliability under harsh conditions.

ROSNOL’s RF attenuators deliver exceptional performance at competitive pricing, making them a cost-effective 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 options are available to meet specialized requirements.
