N Plug (Male) to N Jack (Female) Fixed Attenuator, 6GHz 300W 30dB VSWR 1.35

N Plug to N Jack Fixed Attenuator | 30 dB | 300 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-6G300W30/133-H3 is a high-power fixed attenuator designed for RF and microwave applications up to DC to 6 GHz. This N-type attenuator provides a nominal attenuation of 30 dB with an attenuation deviation of ±1.2 dB, enabling controlled signal reduction under elevated power levels. Rated for 300 watts average power at 25°C, it maintains VSWR ≤ 1.35 (Return Loss ≥ 16.54 dB). The screw-lock coupling mechanism ensures secure mechanical engagement.

Constructed with a nickel-plated brass body, the attenuator incorporates gold-plated phosphor bronze and brass center contacts to ensure reliable electrical performance. PTFE insulation offers stable dielectric characteristics, while a silicone rubber gasket enhances environmental sealing. An aluminum heatsink with black anodized finish improves heat dissipation. Mechanical features include ≥500 mating cycles, axial captivation ≥28 N, coupling test torque ≤1.7 Nm (recommended 0.7–1.1 Nm), and operational temperature range from −55°C to +125°C.

ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-power signal attenuation, ROSNOL attenuators offer a cost-effective alternative to products from leading European and American brands.
