N Fixed Attenuator | Plug (Male) to Jack (Female) | 20 dB | 50 W | DC–18 GHz | Screw‑On | Brass Body
The ROSNOL FA-PCN1PCN25A-18G50W20/H33-H3 fixed attenuator delivers 20 dB attenuation for 50 Ω Precision N systems, operating from DC to 18 GHz with a VSWR of 1.4. It supports 50 W average power and 1000 W peak power, making it suitable for precision RF attenuation in broadband and microwave applications. A screw‑on coupling mechanism, ≥500 mating cycles, and a recommended torque of 1.0 Nm ensure long-term reliability.
Gold‑plated phosphor bronze center contacts and a nickel‑plated brass body ensure electrical and mechanical integrity. PTFE insulation supports dielectric stability, while the silicone gasket and black‑anodized heatsink enhance thermal performance. This model is ideal for power control, calibration systems, and high‑frequency signal conditioning requiring consistent 20 dB attenuation.
ROSNOL components are manufactured in ISO9001-certified facilities and comply with RoHS and REACH regulations. Offering high reliability and competitive pricing, the unit is an excellent alternative to premium global brands, with customization available.
