The Keysight (formerly Agilent HP) 909F is a family of precision low-reflection coaxial loads designed for use as calibration standards. Employing advanced tantalum nitride on sapphire thin-film technology, these loads provide exceptional long-term impedance stability and are available in APC-7, Type-N male, and Type-N female configurations. Their connector contacts feature gold-plated beryllium copper to ensure maximum wear resistance and repeatable performance.
