Description
Precision SMA Fixed Attenuator | Plug (Male) to Jack (Female) | 20 dB | 2 W Power Handling | Screw-Lock | Passivated Stainless Steel Body with Gold-Plated BeCu Contact
The ROSNOL FA-PCA1PCA25A-27G2W20/9XX-9X precision SMA fixed attenuator supports DC to 27 GHz operation with a characteristic impedance of 50 Ω and 2 W average power handling at 25 °C. It provides 20 dB nominal attenuation with controlled attenuation accuracy across the operating frequency range. VSWR is maintained at ≤ 1.25 from DC to 18 GHz and ≤ 1.30 from 18 to 27 GHz. Maximum deviation over frequency is ±0.50 dB from DC to 18 GHz and ±0.80 dB from 18 to 27 GHz. The screw-lock coupling structure ensures secure engagement, consistent signal integrity, and dependable mechanical stability.This attenuator features a precision beryllium copper center contact with gold plating over a nickel underplating to ensure low contact resistance and long service life. A passivated stainless steel body and coupling nut provide enhanced corrosion resistance, while the PTFE insulator and silicone rubber gasket maintain dielectric stability across the −55 °C to +125 °C operating temperature range.
ROSNOL RF attenuators are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH standards. Designed to deliver high-quality RF performance at competitive cost, ROSNOL products serve as dependable alternatives to major European and American brands. Complete customization services, including attenuation levels, materials, plating systems, and mechanical design options, are available to meet specific RF system requirements.
