N Way Power Divider Calculator

This calculator determines the total loss of an N-way power divider, used in RF networks to split a signal across multiple outputs. It makes it possible to know the theoretical loss linked to the number of outputs as well as the additional losses of the path.

Useful for RF engineers, antenna array designers, and electronics students looking to size or evaluate the performance of a multi-way power divider.

Formulas

Loss N = 10 × log10(N)

Total loss = Loss N + Path loss

Explanation of formulas

  • N is the number of outputs of the divider (unitless).
  • Loss N represents the theoretical loss caused by dividing the signal between N outputs.
  • Path loss is additional losses due to wiring or components.
  • The sum gives the total system loss, expressed in dB.

Calculating the loss of a 4-way power divider

Input : N = 4, Path loss = 0.3 dB

Output : Total loss ≈ 6.33 dB

Benefits and uses

  • Allows you to quickly estimate the total loss of a multi-way divider.
  • Useful for designing multiple output amplifiers and antenna arrays.
  • Facilitates the analysis of the overall performance of an RF system.
  • Practical tool for power testing and simulations.
