Abstract

The invention discloses a Ka-band waveguide power divider, which comprises a metal cavity, a printed board substrate, a metal cover plate and three coaxial connectors, wherein the periphery of the metal cavity is provided with three small holes which are and for fixing the coaxial connectors, and the printed board substrate is installed inside the metal cavity; one side of the metal cavity is provided with an opening, and the cover plate covers the opening to seal the metal cavity. The power divider disclosed by the invention has the advantages of high Q value, low radiation loss and high power capacity of a metal waveguide, also has the advantages of convenient integration and processing and low cost of a microstrip line, and has a wide application prospect in the technical field of radiofrequency communication.

Description

technical field [0001] The present application relates to the field of microwave devices, in particular to a Ka-band waveguide power divider. Background technique [0002] The first generation of microwave and millimeter wave systems mainly use metal waveguides as the medium for transmitting electromagnetic waves. Metal waveguides have the advantages of low loss, high Q value, large power capacity, good temperature stability, and strong mechanical structure. Development direction, metal waveguide as a three-dimensional structure, it is difficult to take advantage of the system integration required by miniaturization, it is even more difficult to achieve light weight, and the processing difficulty and production cost are relatively high. [0003] The substrate-integrated waveguide is a new type of microwave and millimeter-wave planar waveguide structure, which not only has the advantages of high Q value, low radiation loss, and high power capacity of metal waveguides, but al...
