Keysight 11667 Series DC Power Splitters
Keysight 11667 Series DC to 18, 26.5, 50, or 67 GHz Power Splitter
The Keysight 11667 series power splitters are recommended when making wideband ratio measurements using a Keysight 8757 scalar network analyzer. The two-resistor type power splitters provide excellent output SWR at the auxiliary arm when used for source leveling or ratio measurement applications. The tracking between output arms over a frequency range from DC to 18, 26.5, or 50 GHz allows wideband measurements to be made with a minimum of uncertainty.
The Keysight 11667L is a 50 Ω two-resistor type power splitter with BNC connectors. It is used with the E5061B network analyzer for power distribution network applications, such as DC-DC converter output impedance measurements with shunt-thru method (100 Hz to 10 MHz). It provides excellent amplitude (<0.2 dB) and phase tracking (±3), ensures highly accurate power splitting and low SWR minimizes measurement uncertainty.

Frequently Asked Questions:
Question: What is the difference between a power divider and a power splitter?
Answer: A power divider and power splitter may, at times, be considered the same device and perform the same functions in an application. But the fact is, they are not interchangeable. The power divider is constructed with equivalent 50 Ωresistance at each port and works bi-directionally, for simple power dividing or power combining applications. In contrast, the power splitter is built with two resistors that provide 50 Ω output impedance, minimizing measurement uncertainties in source levelling or improving effective output match in ratio measurement applications.
