Embodiment Construction

[0017] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] The principle of space power distribution and synthesis structure of the single-sided double-ridge extended waveguide space power distribution and synthesis based on the microstrip probe array adopted by the present invention is as follows: figure 2 shown. In this structure, the electromagnetic wave first enters the broadband extended waveguide from the coaxial waveguide, and then enters each single-sided double-ridge rectangular waveguide from the extended waveguide to complete the power distribution. Each signal entering the rectangular waveguide passes through the rectangular waveguide-microstrip probe array The conversion structure enters the microstrip planar circuit. On the planar ...

Abstract

Provided is a single-face double-ridge spreading waveguide space power distribution synthesizer based on a micro-strip probe array. The synthesizer is provided with a spreading waveguide space power distribution synthesis structure with the characteristics of low loss and wide frequency band. A spreading waveguide is mainly composed of a coaxial step-shaped impedance conversion structure and eight paths of single-face double-ridge rectangular waveguides with high consistency and high-power distribution synthesis efficiency, single-path power amplification of each path of rectangular waveguide can be achieved on a micro-strip circuit through a waveguide-micro-strip probe array conversion structure, and final power synthesis is finished in spreading waveguides. According to the technology, a gain amplification circuit and a power amplification circuit of a power amplifier are arranged outside spreading waveguides, the heat dissipation problem is effectively solved, and system power capacity is greatly improved. The applicable frequency range of the technology can cover a plurality of frequency bands of microwave millimeter waves, an output power can be flexibly adjusted according to bandwidth requirements of different frequency bands through specific power devices.

Description

technical field [0001] The invention relates to a single-sided double-ridge extended waveguide spatial power distribution combiner. Background technique [0002] As an important part of microwave and millimeter wave radar, guidance and communication systems, microwave and millimeter wave solid-state power amplifier has become an important topic in the field of microwave and millimeter wave research. With the continuous improvement of the output power requirements of the amplifier, the output power of a single amplifier chip can no longer meet the needs of the system. Therefore, the technology of multi-channel amplification and power combination must be used to effectively improve the output power of the entire amplifier circuit. [0003] Because the technical solutions adopted by the traditional planar circuit power distribution and synthesis technology are relatively complex in terms of structural realization, it is difficult to solve the problems of reducing loss and effec...
