Description
BNC Fixed Attenuator | 6 dB | 1 W | DC–2 GHz |
The ROSNOL BNC Fixed Attenuator, model FA-B1B25A-2G1W6/H33-H3, delivers consistent RF signal attenuation for 50-ohm systems up to 2 GHz. This model provides a nominal attenuation of 6 dB with a deviation of ±0.3 dB, enabling precise signal level control across broadband frequencies.
With a power rating of 1 watt at 25 °C and a typical VSWR of ≤ 1.20, the attenuator supports stable RF performance in laboratory and system environments. The BNC male to BNC female interface uses a bayonet-lock coupling mechanism, supporting at least 500 mating cycles. Mechanical integrity is ensured through a defined center contact captivation force of ≥ 15 N.
The FA-B1B25A-2G1W6/H33-H3 features gold-plated phosphor bronze center contacts, a nickel-plated brass housing, PTFE dielectric insulation, and silicone rubber gasket elements. All ROSNOL fixed attenuators are produced under ISO 9001-certified manufacturing processes and meet RoHS compliance requirements.
