What Is an RF Power Divider?

An RF power divider distributes an input signal among multiple outputs according to its design. Equal dividers nominally deliver equal branch powers when the ports are properly matched.

How it works in practice

Divider topology determines bandwidth, isolation, impedance behavior and combining suitability. Insertion loss includes unavoidable division loss plus excess loss. Check the defined port arrangement and terminate branches as required. Product photos cannot reveal every internal characteristic.

Example and interpretation

An ideal equal two-way divider sends half the input power to each branch, approximately 3.01 dB below the input.

Checks before use

  • Check port count
  • Check impedance and band
  • Check loss and isolation
  • Terminate branches correctly

Important limit

Do not interpret ideal division loss as a manufacturing defect.
