Key Specifications
Description
N Fixed Attenuator | Plug (Male) to Jack (Female) | 20 dB | 100 W | DC–8.5 GHz | Screw-Lock | Brass Body
The ROSNOL FA-N1N25A-8.5G100W20/H33-H3 fixed attenuator delivers 20 dB attenuation for 50 Ω systems with an N Plug (Male) to N Jack (Female) interface. It operates from DC to 8.5 GHz with a maximum VSWR of 1.35, supports 100 W average power and 5000 W peak power, and features a screw-lock coupling mechanism with a 1.0 Nm recommended torque and ≥500 mating cycles for reliable field and lab use.
Gold-plated phosphor bronze center contacts provide stable electrical performance, while the nickel-plated brass body and coupling nut ensure mechanical durability. PTFE insulation maintains low-loss dielectric behavior, a silicone rubber gasket improves sealing, and the black-anodized aluminum heatsink enhances heat dissipation. This model is ideal for output power control, inter-stage attenuation, and test instrumentation where precise 20 dB attenuation and robust mechanics are required.
Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH, ROSNOL attenuators offer high quality at an affordable price. The FA-N1N25A-8.5G100W20/H33-H3 is a cost-effective alternative to leading international brands, with comprehensive customization services available.
