Description
40 dB Fixed Attenuator | N Plug (Male) to N Jack (Female) | 100 W | DC–4 GHz | VSWR 1.20
The ROSNOL FA-N1N25A-4G100W40-944-94 is a high-power 40 dB fixed attenuator designed for RF and microwave applications requiring accurate signal reduction and stable impedance matching. Featuring N Plug (Male) to N Jack (Female) interfaces, 50 Ω impedance, and an operating frequency range from DC to 4 GHz, this attenuator helps protect sensitive equipment while maintaining signal integrity across communication and test systems.
Engineered for reliable performance, the attenuator provides VSWR ≤1.2 and supports 100 W average power at 25°C. The design incorporates beryllium copper center contacts with gold plating, brass components with copper-tin-zinc alloy plating, PTFE insulation, silicone rubber gaskets, and a black-anodized aluminum heatsink for efficient heat dissipation and long service life.
Its rugged screw-on N connector interface and durable construction make the FA-N1N25A-4G100W40-944-94 suitable for RF testing, wireless infrastructure, broadcast systems, microwave laboratories, and high-power signal conditioning applications.
