Description
SMA Fixed Attenuator | Male to Female | 0 dB | 2 Watt | Screw-Lock | Stainless Steel Body Passivated
The ROSNOL FA-A1A25C-18G2W0/9XX-9X is a precision-engineered fixed attenuator for RF and microwave systems, optimized for attenuation values between 0 and 6 dB. Operating from DC to 18 GHz, it ensures 50 Ω impedance, VSWR ≤ 1.35 (≥16.54 dB return loss), and attenuation accuracy of ±0.30 dB. Rated for 2 Watts average power at 25°C and peak power up to 250 Watts, this attenuator guarantees stable signal control. The screw-lock coupling mechanism provides secure connectivity and mechanical durability for over 500 mating cycles.The center contact is beryllium copper with gold plating over nickel underplating for superior conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, complemented by PTFE insulators and silicone rubber gaskets for environmental sealing. The assembly withstands temperatures from -65°C to +125°C, ensuring long-term reliability.
ROSNOL’s RF attenuators deliver exceptional performance at competitive pricing, offering a cost-effective alternative to leading global brands. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH standards, these attenuators guarantee environmental safety and global regulatory alignment. Customization options for attenuation values, materials, and plating are available to meet specialized requirements.
