摘要： A wide band directional coupler is disclosed. The coupler includes a main transmission line connected between an input port and an output port; and a coupling transmission line having a first length and connected between a coupling port and an isolation port, wherein the coupling transmission line is coupled to the main transmission line through a coupling capacitive connection and a mutual inductive connection, wherein at least a distance between the main transmission line and the coupling transmission line varies along the first length of the coupling transmission line such that any one of a capacitance value of the capacitive connection and an inductance value of the inductive connection is characterized by a relatively low value, wherein a coupling factor of the wide band directional couple remains substantially constant throughout an operating frequency band of the wide band directional coupler.
