The Agilent 909F family of precision low reflection loads is intended for use as calibration standards. Tantalum nitride on sapphire thin-film technology is used for exceptional long-term impedance stability. To ensure the best possible wear resistance characteristics, gold-plated beryllium copper has been used for the connector contacts.

The loads are available in APC-7, type-N (male) and type-N (female) configurations.
