Description
Fixed Attenuator 30 dB | SMA Plug (Male) to SMA Jack (Female) | Screw-Lock | Stainless Steel Body
The ROSNOL FA-A1A25A-18G5W30/9XX-9X is a high-frequency 30 dB fixed attenuator engineered for RF, microwave, aerospace, defense, and test & measurement environments. With DC to 18 GHz operation, 50 Ω impedance, VSWR ≤ 1.2, and 5 W power handling, it delivers accurate attenuation and dependable electrical performance for demanding signal management tasks.Constructed with a passivated stainless steel body, gold-plated beryllium copper contacts, PTFE insulation, stainless steel coupling nut, and black anodized aluminum heatsink, this attenuator combines durability with efficient thermal dissipation. The nominal attenuation is 30 dB with a tolerance of -0.8/+1.0 dB.
ROSNOL's precision-engineered RF attenuators are manufactured in Taiwan under ISO 9001-certified processes and comply with RoHS and REACH standards. Custom design services are available for global RF and microwave projects.
