Splitting a Signal Between Two Receivers

SMA coaxial two-way RF power divider with CentronRF watermark

A divider can feed two receivers from one source if each receives enough signal and the system handles loss, impedance and receiver interaction.

How it works in practice

Check whether either receiver sends bias or leakage into the shared path. Use the appropriate DC isolation and protection when needed. Account for division loss, cables and each receiver's sensitivity. If one branch is disconnected, use the termination arrangement required by the divider.

Example and interpretation

A signal near one receiver's sensitivity limit may fail after adding the approximately 3 dB ideal loss of an equal two-way split.

Checks before use

  • Budget both input levels
  • Check receiver DC behavior
  • Check isolation
  • Terminate a removed branch

Important limit

Do not expect passive splitting to preserve the original power at both outputs.
