Precision SMA Plug (Male) to Precision SMA Jack (Female) Fixed Attenuator, 27GHz 1W 10dB VSWR 1.3

Precision SMA Fixed Attenuator | Plug (Male) to Jack (Female) | 10 dB | 1 W Power Handling | Screw-Lock | Black Anodized Aluminum Heatsink Body with Gold-Plated BeCu Contact

The ROSNOL FA-PCA1PCA25A-27G1W10/9XX-9X precision SMA fixed attenuator supports DC to 27 GHz operation with a 50 Ω impedance and VSWR ≤ 1.3. It delivers a nominal attenuation of 10 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 structure provides secure engagement, stable contact retention, and repeatable mechanical durability with coupling nut retention ≥ 270 N and center contact captivation (axial) ≥ 20 N.

This attenuator features a precision beryllium copper center contact with gold plating over non-magnetic nickel–phosphorus underplating to ensure low insertion loss and long service life. The passivated stainless steel connector body, black anodized aluminum heatsink, PTFE insulator, and silicone rubber gasket offer excellent corrosion resistance and stable performance across −55 °C to +125 °C.

ROSNOL’s precision-engineered RF attenuators are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH requirements. Designed to deliver reliable electrical performance at competitive cost, ROSNOL products represent a dependable alternative to premium European and American RF brands. Full customization services are available for attenuation values, materials, plating, and mechanical configurations.
