3dB Hybrid Ring 3 dB Hybrid Couplers
A 3 dB, 90° hybrid coupler is a four-port device that is used either to equally split an input signal with a resultant 90° phase shift between output signals or to combine two signals while maintaining high isolation between them.
3dB Hybrid Ring 3 dB Hybrid Ring (0°/180°)
A hybrid ring is a four-port device that is used either to equally split an input signal or to sum two combined signals. An additional benefit of the hybrid ring is to alternately provide equally-split but 180 degree phaseshifted output signals.
