Abstract

The invention discloses a miniaturized low-loss large-spacing millimeter wave power division network which comprises a shell. The shell is provided with a first-stage one-to-two power division module, a second-stage one-to-two power division module, a waveguide microstrip converter, a waveguide coaxial converter, a first-stage waveguide transmission line, a second-stage waveguide transmission line, a third-stage waveguide transmission line and a connector. The first end of the first-stage waveguide transmission line is a total port; the first-stage waveguide transmission line is connected with a total port micro-strip of the first-stage one-to-two power division module; two split micro-strips of the first-stage one-to-two power division module are respectively connected to the first end of the second-stage waveguide transmission line; the second end of the second-stage waveguide transmission line is connected with a total port micro-strip of the second-stage one-to-two power division module; two split micro-strips of the second-stage one-to-two power division module are respectively connected to the first end of a third-stage waveguide transmission line through a waveguide micro-strip converter; and the second end of the third-stage waveguide transmission line is a split port. The millimeter wave power division network has the advantages of small size, light weight and low loss.

Description

technical field [0001] The present invention relates to the technical field of power distribution and synthesis network in millimeter wave radar, communication and electronic countermeasure system, in particular to a millimeter wave power distribution network with miniaturization, low loss and large spacing, with equal power divided into one input and four outputs, and the electromagnetic wave energy of the output port is mutually isolated. . Background technique [0002] The power division network has a wide range of applications in military and civilian electronic systems such as radar, electronic countermeasures, and communications. It is an important device for the synthesis and distribution of electromagnetic wave energy. The power division network used in the aerospace field not only requires high reliability but also requires the volume and weight to be as small as possible. [0003] At present, in the millimeter wave band, as a power division network for energy syn...
