Abstract

A millimeter wave 3dB power distributing / synthesizing network comprises a millimeter wave rectangular waveguide, two probes with same shape and structure and two microstrip transmission lines; two probes extend along the rectangular waveguide E-surface face to face and are vertically inserted into the rectangular waveguide from a same opening at the surface of the wide edge of the rectangular waveguide, the plug-in position is symmetrical to the central plane of the wide edge of the rectangular waveguide, and the theoretical space between the center line of the two probes and the waveguide short circuit surface in the conveying direction of the rectangular waveguide is a quarter of the waveguide wavelength. The millimeter wave 3dB power distributing / synthesizing network can realize the conversion of millimeter wave full waveguide band width waveguide to microstrip and power distributing / synthesizing, and has the characters of wide frequency band, low wastage, easy manufacturing, facilitating the installation of the solid device, compact conformation, and conveniently realizing the multiplex distributing / synthesizing.

Description

technical field [0001] The invention belongs to the technical field of millimeter-wave integrated circuits, and in particular relates to a millimeter-wave broadband low-loss waveguide-microstrip 3dB hybrid integrated power distribution and synthesis network. Background technique [0002] In the millimeter-wave solid-state integration technology, an inevitable topic is the transition connection between the millimeter-wave system transmission structure and the millimeter-wave integrated transmission structure—that is, the transition connection between the waveguide and the microstrip. After decades of development, researchers have proposed various waveguide-microstrip transition structures, among which the waveguide-microstrip E-plane probe structure is more representative. It has the advantages of low loss, wide frequency band, easy processing, and easy integration of solid-state devices. It is a waveguide-microstrip transition structure that is wide...
