High-isolation one-to-four phase shift power divider

摘要: The invention discloses a high-isolation one-to-four phase shift power divider, which comprises an input waveguide, waveguide coupler group, section four rectangular waveguide-to-square waveguides, output square waveguides and eight UG-387/U flange plates, wherein the are cascaded with one another, each port connected plate, structure is divided into upper cavity lower fixed through screws positioned pins. divider can be applied to terahertz multi-path feed system signal calibration system, has advantages that high isolation exists between ports, simple, machining easy, meanwhile, any quantity achieved on given frequency, requirement for difference in application met, energy of radiated air, inconvenience caused by use matched load avoided.
