Coherent signals combine according to amplitude and phase, not just arithmetic power addition. Phase error can reduce useful output and increase dissipation elsewhere.
How it works in practice
Analyze the specified network and reference planes. Cable delays and source synchronization affect the phase at each input. A network designed for in-phase combining can behave very differently with opposite-phase inputs. Verify limits for imbalance and fault conditions.
Example and interpretation
Two equal signals arriving 180 degrees apart at a summing point can cancel there rather than produce the desired larger signal.
Checks before use
- Confirm source coherence
- Match phase at the combiner
- Measure amplitude balance
- Check imbalance dissipation
Important limit
Do not assume two equal watt readings guarantee efficient combination.
