The Keysight 11667A is a high-performance, two-resistor coaxial power splitter designed for wideband ratio measurements and source leveling applications. Operating from DC to 18 GHz, it provides excellent amplitude tracking and low equivalent output SWR to minimize measurement uncertainties, particularly when used in conjunction with scalar network analyzers like the Keysight 8757 series.
