Radial waveguide power combiner and assembly method thereof

Abstract

The invention discloses a radial waveguide power combiner and an assembly method thereof, wherein the microwave of the waveguide input port is conducted into the radial waveguide through a probe of the radial waveguide power combiner, and the microwave is uniformly distributed to every channel according to the radial waveguide characteristics. The probe adopts a plug-in type fixing method, that is, a first locating pin is arranged on the upper end of the probe and is inserted into a first locating hole of an upper cover plate, and a second locating pin is arranged on the lower end of the probe and is inserted into a second locating hole of a lower cover plate. The above design has advantages of guaranteeing the stability of the overall structure, positioning accurately, reducing the assembling error, and making the index more accurate than before. Compared with the present power combiner, the radial waveguide power combiner is simpler and more stable in structure, easier to realize, wider in frequency band, lower in insertion loss, and more suitable for using in microwave millimeter-wave power combing application field.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a radial waveguide power combiner and an assembly method thereof. Background technique [0002] In recent years, with the rapid development of the communication industry, the requirements for the bandwidth, transmission rate and transmission distance of the communication system have become higher and higher. As an important part of the communication system, power amplifiers require increasing bandwidth, efficiency and output power. However, due to the influence of the physical characteristics of the millimeter-wave solid-state device itself and the limitations of the processing technology, it is still difficult to produce high-power, low-noise and low-cost millimeter-wave solid-state power devices. The research of millimeter-wave solid-state power synthesis technology has become the main way to solve this problem and has a wide range of application values. [0003] At pres...

AI Technical Summary

Problems solved by technology

For the application of power synthesis in the solid-state power transmission of millimeter-wave radar, the number of solid-state devices that can be synthesized is limited due to transmission line loss and circuit structure increasing non-linearly with the increase of the number of devices, which cannot meet the transmission power requirements of millimeter-wave radar.

The biggest advantage of space power combination is that the combination efficiency is basically independent of the number of solid-state devices, and it is more suitable for high-power output of multiple devices, but it also cannot meet the transmission power requirements of millimeter-wave radars, and cannot effectively solve the problem of high-power output in high-frequency bands. problem
