Description
Precision N Fixed Attenuator | Male to Female | 7 dB | 2 W | Stainless Steel Body
The ROSNOL FA-PCN1PCN25A-18G2W7/9XX-9X precision N fixed attenuator supports DC to 18 GHz operation at 50 Ω with band-specific VSWR performance: ≤ 1.11 from DC–6 GHz, ≤ 1.15 from 6–12.4 GHz, and ≤ 1.25 from 12.4–18 GHz. It provides a nominal 7 dB attenuation with deviation of ±0.3 dB (DC–4 GHz), ±0.4 dB (4–8 GHz), ±0.5 dB (8–12.4 GHz), and ±0.8 dB (12.4–18 GHz). Average power handling is 2 W up to 30 °C. The screw-lock coupling delivers secure engagement, stable contact retention, and durable mechanical performance over repeated mating cycles, ensuring predictable attenuation and power accuracy across the specified band.Piece-part construction employs a beryllium copper (BeCu) center contact with gold plating over nickel underplating, a passivated stainless steel body and coupling nut, PTFE insulator, and silicone rubber gasket. This materials stack offers strong corrosion resistance and dielectric stability over the operating temperature range of −55 °C to +130 °C. The plating system (gold over nickel underplate) ensures low contact resistance and long-term reliability in precision N interconnects.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems.
