Multipath microwave power distribution device based on coaxial waveguide

Abstract

The invention discloses a coaxial waveguide-based multipath microwave power distribution device, and the device comprises an outer conductor housing which comprises an annular housing side body and a bottom plate; an inner conductor piece and a stepped circular truncated cone conductor piece; a plurality of openings are formed in the area, close to the bottom plate, of the shell side body; the plurality of output end inner conductor rods are in one-to-one correspondence with the plurality of openings, one ends of the output end inner conductor rods are fixedly connected with the first side wall, and the other ends of the output end inner conductor rods extend into the openings; an output end space channel is formed between the output end inner conductor rod and the side wall of the opening, an input end space channel is formed between the inner conductor piece and the inner side wall of the shell side body, and a transition space channel is formed between the stepped circular truncated cone conductor piece and the inner side wall of the shell side body. The loss is lower and the power capacity is higher; microwave multi-path one-stage distribution is realized, multi-path microwave output can be obtained without adopting a cascade mode, and microwave loss caused by cascade is avoided; the device has the advantages of simple structure and integration.

Description

technical field [0001] The invention relates to the technical field of microwave solid state power distribution, in particular to a multi-channel microwave power distribution device based on a coaxial waveguide. Background technique [0002] In solid-state high-power microwave technology, the output power of a single solid-state device is far from meeting the requirements of high-power applications due to the influence of its own semiconductor physical characteristics and the limitations of processing technology, heat dissipation, and impedance matching. In order to solve this problem, a method of power distribution, amplification and recombination of multiple solid-state devices is usually used to obtain high power output. [0003] A power divider is a microwave passive device that divides a microwave signal into multiple microwave signals; conversely, it can also combine multiple microwave signals into one, which is used as a combiner at this time. Such devices play a ver...
