The rat race coupler is a simple method of realizing a 180 degree hybrid coupler. However, it has a narrow bandwidth on the order of 20%. One method of realizing a wideband 180 degree hybrid is to use asymmetric coupled transmission lines. These couplers commonly realize 10:1 bandwidth ratios.180° hybrid ring couplers (also called “rat race” couplers) are four-port devices used to either 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 phase-shifted output signals.hybrid coupler towards the PAs, undergoing an additional degree90- phase change.
