Description
BNC Fixed Attenuator | 10 dB | 1 W | DC–2 GHz
The ROSNOL BNC Fixed Attenuator, model FA-B1B25A-2G1W10/H33-H3, is engineered for reliable RF attenuation in broadband 50-ohm applications from DC to 2 GHz. This attenuator offers a nominal attenuation value of 10 dB with an accuracy of ±0.5 dB, supporting controlled signal reduction where higher attenuation levels are required.
The device is rated for an average power handling of 1 watt at 25 °C and exhibits a typical VSWR of ≤ 1.20 to maintain low signal reflection. The BNC plug (male) to BNC jack (female) configuration incorporates a bayonet-lock coupling mechanism with a mechanical durability of at least 500 mating cycles and a center contact captivation force of ≥ 15 N.
The FA-B1B25A-2G1W10/H33-H3 is built with gold-plated phosphor bronze center contacts, a nickel-plated brass body, PTFE insulation, and silicone rubber sealing components. This product is manufactured in ISO 9001-certified facilities and is fully compliant with RoHS standards.
