The invention discloses a broadband phase shifting power divider with an amplitude and phase compensating function, and belongs to the technical field of microwaves. The cascaded Wilkinson power division scheme is adopted for the power divider, and the power divider is provided with (2m+1) (m is an integer greater than 1) ports, wherein the port 1 is an input port, and the ports 2 to (2m+1) are output ports. The power divider is capable of realizing 2m paths of outputs equal in amplitude and arbitrary in phase difference on an input signal, and has broadband characteristics. According to the broadband phase shifting power divider with the amplitude and phase compensating function, an interstage transmission line of a certain length is arranged between the stages of the cascaded Wilkinson power divider, and a parallel open circuit and (or) short circuit branches (branch) is loaded, and the common bandwidth of the amplitude and phase imbalance of the phase shifting power divider can be greatly increased by virtue of reasonable design of the parameters of the interstage transmission line and the branches; meanwhile, the broadband phase shifting power divider also has excellent port isolation and echo characteristics. The broadband phase shifting power divider with the amplitude and phase compensating function is applicable to the feed network of an array antenna, a balancing amplifying circuit and other microwave circuits and systems.
