180 deg Hybrid In-Phase Splitting

The 180 deg Hybrid (also called a Rat Race Coupler) shown here is a common microwave component that allows power to be split or combined with control over the phase. This video shows one input signal being split into two output signals. Because the signal is input to the 'Sum' or 'in-phase' port it is split to the two 'input' ports with equal magnitude and phase. You can see that the phases are the same from the E-field vectors which point in the same direction on both outgoing ports.

See our other videos for some examples of how to use 180 deg hybrids to split a signal into two 180 degrees out of phase signals and how to add and subtract two input signals.
