N Plug (Male) to N Jack (Female) Fixed Attenuator, 6GHz 500W 30dB VSWR 1.35

N Male to N Female Fixed Attenuator | 30 dB | 500 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-6G500W30/133-H3 is a high-power fixed attenuator designed for RF and microwave systems operating up to DC to 6 GHz. This N-type attenuator delivers a nominal attenuation of 30 dB with an attenuation deviation of −1.2/+1.5 dB, ensuring controlled signal reduction under high-power conditions. Rated for 500 watts average power at 25°C, it maintains VSWR ≤ 1.35 (Return Loss ≥ 16.54 dB). The screw-lock coupling mechanism provides secure and reliable mechanical connection.

Manufactured with a brass body featuring nickel plating, the attenuator incorporates phosphor bronze and brass center contacts with gold plating to optimize conductivity and durability. PTFE insulation ensures stable dielectric performance, while a silicone rubber gasket improves environmental sealing. An aluminum heatsink with black anodized finish enhances thermal dissipation. Mechanical specifications include ≥500 mating cycles, coupling nut retention ≥450 N, axial captivation ≥28 N, and coupling test torque up to 1.70 Nm (recommended 0.7–1.1 Nm). Operating temperature ranges from −55°C to +125°C.
