WebThe branch line coupler is a signal coupler or divider which has four ports. The geometry of the coupler is shown in Figure1. The signal fed to port 1 is split equally into port 3 and 4 with one of the outputs exhibiting a 90 phase shift. The port 2 is an isolated port. The design specifications of the coupler are shown in Table.1.
