The operational principle of a 0-degree power splitter.

The operational principle of a 0-degree power splitter.

The core working principle of a 0° power divider lies in its specific circuit design, which enables the distribution of input signal energy (or the synthesis of multiple signals) while ensuring strict phase coherence (0° phase difference) across all output ports. Its implementation relies on transmission line characteristics, impedance matching, and isolation design. Below is a detailed explanation from four aspects: signal distribution, phase control, impedance matching, and isolation mechanisms.
