N Plug (Male) to N Jack (Female) Fixed Attenuator, 6GHz 50W 20dB VSWR 1.2

N Male to N Female Fixed Attenuator | 20 dB | 50 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-6G50W20/933-93 is a precision-engineered fixed attenuator for RF and microwave systems requiring reliable mid-level attenuation. This N-type attenuator provides a nominal attenuation of 20 dB with an attenuation deviation of ±0.4 dB, ensuring accurate and repeatable signal control across DC to 6 GHz. Rated for 50 watts average power at 25°C and specified VSWR ≤ 1.20 (Return Loss ≥ 20.83 dB), it maintains low reflections and stable impedance matching. Peak power capability reaches 5000 W (5 μs pulse width, 1% duty cycle). The screw-lock coupling mechanism guarantees secure mating under routine test cycles.

Manufactured with a nickel-plated brass body for durability, the design incorporates a beryllium copper center contact with gold plating over a non-magnetic nickel-phosphorus underlayer to optimize conductivity and corrosion resistance. PTFE insulation delivers excellent dielectric properties, while a silicone rubber gasket improves environmental sealing. An aluminum heatsink with black anodized finish enhances thermal management under sustained load. Mechanical integrity is supported by coupling nut retention ≥450 N, axial captivation ≥28 N, and coupling test torque up to 1.70 Nm (recommended 0.7–1.1 Nm).
