The Keysight (Agilent) 11667A is a two-resistor type power splitter engineered for RF and microwave source leveling and ratio measurement applications. Operating from DC to 18.0 GHz, it delivers exceptional output SWR and maintains consistent tracking between output arms across its full frequency range, enabling wideband measurements with minimal uncertainty. The device integrates with scalar network analyzers for precision RF characterization.
