Power Splitter Troubleshooting: Unequal Output Levels

SMA coaxial two-way RF power divider with CentronRF watermark

Check cable, connector, load and sensor differences before concluding that the divider is unbalanced. Use a repeatable comparison method.

How it works in practice

Swap measurement cables or sensors while maintaining safe connections and matching conditions. If the difference follows a cable, investigate that cable. If it stays with one divider port, compare against model specifications. Verify the source is stable during sequential readings.

Example and interpretation

A 1 dB branch difference that moves when cables are swapped points to the cables or their interfaces, not necessarily the divider.

Checks before use

  • Stabilize the source
  • Check terminations
  • Swap comparison paths
  • Measure divider balance separately

Important limit

Do not compare readings taken with different uncorrected sensor paths.
