Keysight (Agilent) 11667C

The Keysight 11667C is a precision two-resistor power splitter engineered for RF and microwave test applications requiring stable source leveling and wideband ratio measurements. This DC to 50 GHz device splits input signals across two output arms with exceptional tracking performance, making it ideal for scalar network analyzer systems like the Keysight 8757. The 11667C delivers 8.5 dB insertion loss with 0.40 dB tracking between ports, ensuring minimal measurement uncertainty across its entire frequency range. All ports feature 2.4 mm female connectors and 50-ohm impedance matching standard test environments.
