RF Directional coupler will have 4 ports, input port, transmitted port, isolated port and coupled port. For the directional coupler mentioned in the figure, coupled port will have 10 dB power less than the power fed at the INPUT PORT. Transmitted port will have power slightly less than the Input port and will depend on insertion loss between these ports. Isolated port is terminated to 50 Ohm impedance.
