Directional bridge vs coupler
The standard 3 dB hybrid transformer is shown in figure 16. Power at port 1 is split equally between ports 2 and 3 but in antiphase to each other. The hybrid transformer is therefore a 180° hybrid. The centre-tap is usually terminated internally but it is possible to bring it out as port 4; in which case the hybrid can be used as a sum and difference hybrid. However, port 4 presents as a differe… WebDefinition: Directional Coupler is a passive network that is used to measure the microwave power delivered to the load. It is a waveguide with 4-ports which aims at sampling of …
