Power Divider Calculator

This page provides a power divider calculator as part of a larger suite of converters and calculators. The calculator determines the path loss to each port, based on the number of output ports.

Power Divider Calculator Examples:

• 2-way power divider:

  • Number of output ports = 2
  • Path loss = 3 dB

• 8-way power divider:

  • Number of output ports = 8
  • Path loss = 9 dB

Power Divider Calculator Equation

A power divider is a circuit that accepts one RF input signal and splits it into multiple output signals. It’s commonly used in systems where a single RF signal needs to be distributed to several devices.

For instance, in a satellite earth station, multiple signals might be received and need to be distributed across different satellite modems. In such a scenario, an RF power divider is employed after the RF downconverter (which has a single port). The RF power divider divides the single input signal into multiple signals, which are then connected to the IF inputs of the demodulator portion of the modems.

The following equation or formula is used in the power divider calculator:
