Chapter7_mPower Divider and Directional Coupler Introduction A 3-port or 4-port network for power dividing and combining. 3-port: T-junction. 4-port: directional couplers and hybrids. Power dividers are often of equal power division. Directional couplers can be designed for arbitrary power division. Hybrid junctions usually have equal power division and a phase shift of 90o or 180o between the output ports.
