Description
Precision N Fixed Attenuator | 10 dB | 1 W | DC–18 GHz
The ROSNOL Precision N Fixed Attenuator, model FA-PCN1PCN25A-18G1W10/H33-H3, delivers reliable RF signal attenuation for broadband systems up to 18 GHz. This model provides a nominal attenuation of 10 dB with a deviation of ±1.0 dB, enabling controlled and repeatable signal level adjustment in high-frequency applications.With a power rating of 1 watt at 25 °C and a typical VSWR of ≤ 1.35, the attenuator supports stable RF performance. The precision N male to precision N female interface adopts a screw-on coupling mechanism, supporting at least 500 mating cycles, a coupling nut retention force of ≥ 450 N, and defined axial center contact captivation for mechanical reliability.
The FA-PCN1PCN25A-18G1W10/H33-H3 features gold-plated phosphor bronze center contacts, a nickel-plated brass housing, and PTFE dielectric insulation. All ROSNOL precision attenuators are produced in ISO 9001-certified facilities and comply with RoHS standards.
