Quadrature hybrid coupler
A common application of a hybrid coupler is for splitting an input signal into two output signals. A quadrature hybrid provides a 90 relative phase difference ...Quadrature hybrids have inherent -90⁰ phase shifts for each “leg” traversed by a signal, whether used as a power splitter (or “divider”) or as a combiner. An ideal quadrature hybrid will split the power of the RF input signal equally, applying half to each of two output ports, and delivering exactly zero power to the fourth, isolated port.
