Precision SMA Plug (Male) to Precision SMA Jack (Female) Fixed Attenuator, 27GHz 1W 6dB VSWR 1.3

Precision SMA Fixed Attenuator | Plug (Male) to Jack (Female) | 6 dB | 1 W Power Handling | Screw-Lock | Black Anodized Aluminum Heatsink Body with Gold-Plated BeCu Contact

The ROSNOL FA-PCA1PCA25A-27G1W6/9XX-9X precision SMA fixed attenuator operates from DC to 27 GHz with a characteristic impedance of 50 Ω and VSWR ≤ 1.3. It provides a nominal attenuation of 6 dB with a deviation of ±0.5 dB at 27 GHz and supports 1 W average power handling at 25 °C. The screw-lock coupling mechanism ensures secure mating with coupling nut retention ≥ 270 N, center contact captivation (axial) ≥ 20 N, and a minimum of 500 mating cycles, delivering reliable electrical and mechanical performance for RF systems.

The attenuator integrates a beryllium copper center contact with gold plating over non-magnetic nickel–phosphorus underplating (3 µinch Au over 80 µinch Ni–P) to maintain low contact resistance and long-term signal stability. The connector body and coupling nut are manufactured from passivated stainless steel, while a black anodized aluminum heatsink body enhances thermal dissipation. A PTFE insulator and silicone rubber gasket provide stable dielectric performance and corrosion resistance across an operating temperature range of −55 °C to +125 °C.

ROSNOL’s RF attenuators are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Offering consistent RF performance, robust construction, and competitive pricing, ROSNOL attenuators provide a cost-effective alternative to leading European and American brands. Customization services for attenuation values, materials, plating systems, and mechanical design are available to meet specialized RF requirements.
