Description
N Plug (Male) to N Jack (Female) Fixed Attenuator | DC-3GHz | 500W | 20dB | VSWR 1.30
he FA-N1N25A-3G500W20/133-93 is a high-power RF fixed attenuator designed for signal control, impedance matching, and power management in demanding RF and microwave systems. Featuring an N Male to N Female interface and a 50-ohm impedance, this attenuator operates from DC to 3 GHz and supports applications requiring reliable attenuation in communication, broadcast, and test environments.
This model provides 20 dB nominal attenuation with a deviation of -1.0 dB/+1.2 dB while maintaining a VSWR of ≤1.3 across the operating frequency range. Rated for 500 W average power at 25°C, it delivers dependable high-power performance while helping protect downstream equipment and optimize signal levels.
The attenuator incorporates gold-plated beryllium copper and brass contacts, nickel-plated brass bodies, PTFE insulation, silicone rubber sealing elements, and a black-anodized aluminum heatsink for efficient thermal dissipation. It supports at least 500 mating cycles and operates from -55°C to +125°C.
Typical applications include RF communication infrastructure, power amplifier testing, antenna feed systems, broadcast networks, laboratory equipment, and industrial RF installations requiring high-power attenuation.
